    Outlining the skin-homing and circulating CLA+NK cells in patients with severe atopic dermatitis
    (2024) LIMA, Josenilson Feitosa de; TEIXEIRA, Franciane Mouradian Emidio; RAMOS, Yasmim alefe Leuzzi; CARVALHO, Gabriel Costa de; BRANCO, Anna Claudia Calvielli Castelo; PEREIRA, Naiura Vieira; SOTTO, Mirian Nacagami; AOKI, Valeria; SATO, Maria Notomi; ORFALI, Raquel Leao
    Atopic dermatitis (AD) is a complex, multifactorial skin disease, characterized by pruritus and predominant Th2 inflammation. Innate immune cells may play a role in AD development and are composed of granulocytes, macrophages, innate-like T cells, and innate lymphoid cells. This study investigates the phenotypic and functional profile of circulating CLA(+) natural killer (NK) cells and its role in the skin-homing to NK cells infiltrated in adults' skin with AD. We selected 44 AD patients and 27 non-AD volunteers for the study. The results showed increased frequencies of both CLA(+)CD56(bright) and CLA(+)CD56(dim) NK cell populations in the peripheral blood, mainly in severe AD patients. Upon SEB stimulation, we observed an augmented percentage of CLA(+)CD56(dim) NK cells expressing CD107a, IFN-gamma, IL-10, and TNF, reinforcing the role of staphylococcal enterotoxins in AD pathogenesis. Additionally, we demonstrated increased dermal expression of both NK cell markers NCAM-1/CD56 and pan-granzyme, corroborating the skin-homing, mostly in severe AD. Further studies are necessary to elucidate the potential role of NK cells in the chronification of the inflammatory process in AD skin, as well as their possible relationship with staphylococcal enterotoxins, and as practicable therapeutic targets.

    Enhanced immunogenicity and protective efficacy in mice following a Zika DNA vaccine designed by modulation of membrane-anchoring regions and its association to adjuvants
    (2024) TEIXEIRA, Franciane Mouradian Emidio; OLIVEIRA, Luana de Mendonca; BRANCO, Anna Claudia Calvielli Castelo; ALBERCA, Ricardo Wesley; SOUSA, Emanuella Sarmento Alho de; LEITE, Bruno Henrique de Sousa; ADAN, Wenny Camilla dos Santos; DUARTE, Alberto Jose da Silva; LINS, Roberto Dias; SATO, Maria Notomi; VIANA, Isabelle Freire Tabosa
    Zika virus (ZIKV) is a re-emerging pathogen with high morbidity associated to congenital infection. Despite the scientific advances since the last outbreak in the Americas, there are no approved specific treatment or vaccines. As the development of an effective prophylactic approach remains unaddressed, DNA vaccines surge as a powerful and attractive candidate due to the efficacy of sequence optimization in achieving strong immune response. In this study, we developed four DNA vaccine constructs encoding the ZIKV prM/M (pre-membrane/membrane) and E (envelope) proteins in conjunction with molecular adjuvants. The DNA vaccine candidate (called ZK_Delta STP), where the entire membrane-anchoring regions were completely removed, was far more immunogenic compared to their counterparts. Furthermore, inclusion of the tPA-SP leader sequence led to high expression and secretion of the target vaccine antigens, therefore contributing to adequate B cell stimulation. The ZK_Delta STP vaccine induced high cellular and humoral response in C57BL/6 adult mice, which included high neutralizing antibody titers and the generation of germinal center B cells. Administration of ZK-Delta STP incorporating aluminum hydroxide (Alum) adjuvant led to sustained neutralizing response. In consistency with the high and long-term protective response, ZK_Delta STP+Alum protected adult mice upon viral challenge. Collectively, the ZK_Delta STP+Alum vaccine formulation advances the understanding of the requirements for a successful and protective vaccine against flaviviruses and is worthy of further translational studies.

    LAMP-1 Chimeric to HIV-1 p55Gag in the Immunization of Neonate Mice Induces an Early Germinal Center Formation and AID Expression
    (2022) TEIXEIRA, Franciane Mouradian Emidio; OLIVEIRA, Luana de Mendonca; PIETROBON, Anna Julia; SALLES, Erika Machado de; LIMA, Maria Regina D'Imperio; VIANA, Isabelle Freire Tabosa; LINS, Roberto Dias; RIGATO, Paula Ordonhez; MARQUES, Ernesto Torres de Azevedo; DUARTE, Alberto Jose da Silva; SATO, Maria Notomi
    Neonates have a limited adaptive response of plasma cells, germinal center (GC) B cells, and T follicular helper cells (T-FH). As neonatal vaccination can be an important tool for AIDS prevention, these limitations need to be overcome. Chimeric DNA vaccine encoding p55Gag HIV-1 protein conjugated with lysosomal-associated membrane protein 1 (LAMP-1) has been described as immunogenic in the neonate period. Herein, we investigated the immunologic mechanisms involved in neonatal immunization with a LAMP-1/p55Gag (LAMP/Gag) DNA vaccine in a C57BL/6 mouse background. Neonatal LAMP/Gag vaccination induced strong Gag-specific T-cell response until adulthood and elevated levels of anti-Gag IgG antibodies. We also demonstrated for the first time that the immunogenicity of the neonatal period with LAMP/Gag is due to the induction of high-affinity anti-p24 IgG antibodies and long-term plasma cells. Together with that, there is the generation of early TFH cells and the formation of GC sites with the upregulation of activation-induced cytidine deaminase (AID) enzyme mRNA and protein expression in draining lymph nodes after neonatal LAMP/Gag vaccination. These findings underscore that the LAMP-1 strategy in the chimeric vaccine could be useful to enhance antibody production even in the face of neonatal immaturity, and they contribute to the development of new vaccine approaches for other emerging pathogens at an early stage of life.

    Severe COVID-19 patients show a dysregulation of the NLRP3 inflammasome in circulating neutrophils
    (2023) LEAL, Vinicius N. C.; ANDRADE, Milena M. S.; TEIXEIRA, Franciane M. E.; CAMBUI, Raylane A. G.; ROA, Mariela E. G. V.; MARRA, Leticia G.; YAMADA, Suemy M.; ALBERCA, Ricardo W.; GOZZI-SILVA, Sarah C.; YENDO, Tatiana M.; NETTO, Lucas C.; DUARTE, Alberto J. S.; SATO, Maria N.; PONTILLO, Alessandra
    SARS-CoV-2 triggers inflammasome-dependent release of pro-inflammatory cytokine IL-1 beta and pyroptosis, therefore, contributes to the huge inflammatory response observed in severe COVID-19 patients. Less is known about the engagement of inflammasome in neutrophils, main players in tissue injury and severe infection. We studied the activation of the inflammasome in neutrophils from severe COVID-19 patients and assessed its consequence in term of cells contribution to disease pathogenesis. We demonstrated that NLRP3 inflammasome is dramatically activated in neutrophils from severe COVID-19 patients and that the specific inhibition of NLRP3 reverts neutrophils' activation. Next, the stimulation of severe patients' neutrophils with common NLRP3 stimuli was not able to further activate the inflammasome, possibly due to exhaustion or increased percentage of circulating immature neutrophils. Collectively, our results demonstrate that the NLRP3 inflammasome is hyperactivated in severe COVID-19 neutrophils and its exhaustion may be responsible for the increased susceptibility to subsequent (and possibly lethal) infections. Our findings thus include a novel piece in the complex puzzle of COVID-19 pathogenesis.

    COVID-19 Disease Course in Former Smokers, Smokers and COPD Patients
    (2021) ALBERCA, Ricardo Wesley; LIMA, Julia Cataldo; OLIVEIRA, Emily Araujo de; GOZZI-SILVA, Sarah Cristina; RAMOS, Yasmim Alefe Leuzzi; ANDRADE, Milena Mary de Souza; BESERRA, Danielle Rosa; OLIVEIRA, Luana de Mendonca; BRANCO, Anna Claudia Calvielli Castelo; PIETROBON, Anna Julia; PEREIRA, Natalli Zanete; TEIXEIRA, Franciane Mouradian Emidio; FERNANDES, Iara Grigoletto; DUARTE, Alberto Jose da Silva; BENARD, Gil; SATO, Maria Notomi
    The severe respiratory and systemic disease named coronavirus disease-2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Currently, the COVID-19 pandemic presents a huge social and health challenge worldwide. Many different risk factors are associated with disease severity, such as systemic arterial hypertension, diabetes mellitus, obesity, older age, and other co-infections. Other respiratory diseases such as chronic obstructive pulmonary disease (COPD) and smoking are common comorbidities worldwide. Previous investigations have identified among COVID-19 patients smokers and COPD patients, but recent investigations have questioned the higher risk among these populations. Nevertheless, previous reports failed to isolate smokers and COPD patients without other comorbidities. We performed a longitudinal evaluation of the disease course of smokers, former smokers, and COPD patients with COVID-19 without other comorbidities, from hospitalization to hospital discharge. Although no difference between groups was observed during hospital admission, smokers and COPD patients presented an increase in COVID-19-associated inflammatory markers during the disease course in comparison to non-smokers and former smokers. Our results demonstrated that smoking and COPD are risk factors for severe COVID-19 with possible implications for the ongoing pandemic.

    Impact of Inflammatory Immune Dysfunction in Psoriasis Patients at Risk for COVID-19
    (2021) YENDO, Tatiana Mina; SATO, Maria Notomi; BRANCO, Anna Claudia Calvielli Castelo; PIETROBON, Anna Julia; TEIXEIRA, Franciane Mouradian Emidio; RAMOS, Yasmim alefe Leuzzi; ALBERCA, Ricardo Wesley; VALENCIO, Cesar Giudice; ARRUDA, Vivian Nunes; ROMITI, Ricardo; ARNONE, Marcelo; HIRAYAMA, Andre Luis da Silva; DUARTE, Alberto Jose da Silva; AOKI, Valeria; ORFALI, Raquel Leao
    Psoriasis is an immune-mediated dermatosis usually associated with comorbidities. Treatment varies from topicals to systemic drugs and data on susceptibility to viral infections in psoriatic patients are scarce. The objectives of this study were to analyze psoriatic patients on different therapies who were at risk for COVID-19 for seroprevalence of SARS-COV-2, pro-inflammatory cytokine profile, comorbidities and outcomes in order to unveil the immunological mechanisms involved in the anti-viral response in patients with psoriasis. Seventy-five patients with psoriasis were divided according to treatment: immunobiologics, methotrexate, topicals and acitretin. Twenty healthy controls were included. Plasma samples were collected for: IgG SARS-COV-2 (ELISA); IL-27, IL-29 and IL-18 (ELISA); and IL-1 beta, IL-17A, IL-6 and TNF (cytometric array). Seropositivity for SARS-COV-2 was detected in 24 out of 75 psoriasis patients and did not relate to COVID-19 symptoms and/or hospitalization, despite associated comorbidities. Psoriasis patients who were asymptomatic for SARS-COV-2 exhibited immune imbalance with high levels of IL-18, IL-17A and IL-6, and low levels of IL-27 compared to healthy controls. Psoriasis groups showed significant increased cytokine levels only in the group with immunobiologics. Despite immune deviations and lower IL-27, which has a potential antiviral impact, psoriatic patients did not exhibit complications related to COVID-19. An understanding of this kind of proinflammatory profile of psoriatic patients and of the lack of severe outcomes for COVID-19 is essential to establish novel therapeutic approaches and preventive measures, including with regard to the concomitance of viral infections.

    SARS-CoV-2 Infection and CMV Dissemination in Transplant Recipients as a Treatment for Chagas Cardiomyopathy: A Case Report
    (2021) GOZZI-SILVA, Sarah Cristina; BENARD, Gil; ALBERCA, Ricardo Wesley; YENDO, Tatiana Mina; TEIXEIRA, Franciane Mouradian Emidio; OLIVEIRA, Luana de Mendonca; BESERRA, Danielle Rosa; PIETROBON, Anna Julia; OLIVEIRA, Emily Araujo de; BRANCO, Anna Claudia Calvielli Castelo; ANDRADE, Milena Mary de Souza; FERNANDES, Iara Grigoletto; PEREIRA, Natalli Zanete; RAMOS, Yasmim Alefe Leuzzi; LIMA, Julia Cataldo; PROVENCI, Bruna; MANGINI, Sandrigo; DUARTE, Alberto Jose da Silva; SATO, Maria Notomi
    Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 has infected over 90 million people worldwide, therefore it is considered a pandemic. SARS-CoV-2 infection can lead to severe pneumonia, acute respiratory distress syndrome (ARDS), septic shock, and/or organ failure. Individuals receiving a heart transplantation (HT) may be at higher risk of adverse outcomes attributable to COVID-19 due to immunosuppressives, as well as concomitant infections that may also influence the prognoses. Herein, we describe the first report of two cases of HT recipients with concomitant infections by SARS-CoV-2, Trypanosoma cruzi, and cytomegalovirus (CMV) dissemination, from the first day of hospitalization due to COVID-19 in the intensive care unit (ICU) until the death of the patients.

    Clinical Characteristics and Survival Analysis in Frequent Alcohol Consumers With COVID-19
    (2021) ALBERCA, Ricardo Wesley; RIGATO, Paula Ordonhez; RAMOS, Yasmim Alefe Leuzzi; TEIXEIRA, Franciane Mouradian Emidio; BRANCO, Anna Claudia Calvielli; FERNANDES, Iara Grigoletto; PIETROBON, Anna Julia; DUARTE, Alberto Jose da Silva; AOKI, Valeria; ORFALI, Raquel Leao; SATO, Maria Notomi
    Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection can generate a systemic disease named coronavirus disease-2019 (COVID-19). Currently, the COVID-19 pandemic has killed millions worldwide, presenting huge health and economic challenges worldwide. Several risk factors, such as age, co-infections, metabolic syndrome, and smoking have been associated with poor disease progression and outcomes. Alcohol drinking is a common social practice among adults, but frequent and/or excessive consumption can mitigate the anti-viral and anti-bacterial immune responses. Therefore, we investigated if patients with self-reported daily alcohol consumption (DAC) presented alteration in the immune response to SARS-CoV-2. We investigated 122 patients with COVID-19 (101 male and 46 females), in which 23 were patients with DAC (18 men and 5 women) and 99 were non-DAC patients (58 men and 41 women), without other infections, neoplasia, or immunodeficiencies. Although with no difference in age, patients with DAC presented an increase in severity-associated COVID-19 markers such as C-reactive protein (CRP), neutrophil count, and neutrophil-to-lymphocyte ratio. In addition, patients with DAC presented a reduction in the lymphocytes and monocytes counts. Importantly, the DAC group presented an increase in death rate in comparison with the non-DAC group. Our results demonstrated that, in our cohort, DAC enhanced COVID-19-associated inflammation, and increased the number of deaths due to COVID-19.

    I mmunosenescence and Inflammaging: Risk Factors of Severe COVID-19 in Older People
    (2020) PIETROBON, Anna Julia; TEIXEIRA, Franciane Mouradian Emidio; SATO, Maria Notomi
    Old individuals are more susceptible to various infections due to immunological changes that occur during the aging process. These changes named collectively as ""immunosenescence"" include decreases in both the innate and adaptive immune responses in addition to the exacerbated production of inflammatory cytokines. This scenario of immunological dysfunction and its relationship with disease development in older people has been widely studied, especially in infections that can be fatal, such as influenza and, more recently, COVID-19. In the current scenario of SARS-CoV-2 infection, many mechanisms of disease pathogenesis in old individuals have been proposed. To better understand the dynamics of COVID-19 in this group, aspects related to immunological senescence must be well elucidated. In this article, we discuss the main mechanisms involved in immunosenescence and their possible correlations with the susceptibility of individuals of advanced age to SARS-CoV-2 infection and the more severe conditions of the disease.

    Upregulation of PD-1 Expression and High sPD-L1 Levels Associated with COVID-19 Severity
    (2022) BESERRA, Danielle Rosa; ALBERCA, Ricardo Wesley; BRANCO, Anna Claudia Calvielli Castelo; OLIVEIRA, Luana de Mendonca; ANDRADE, Milena Mary de Souza; GOZZI-SILVA, Sarah Cristina; TEIXEIRA, Franciane Mouradian Emidio; YENDO, Tatiana Mina; DUARTE, Alberto Jose da Silva; SATO, Maria Notomi
    COVID-19 has several mechanisms that can lead to lymphocyte depletion/exhaustion. The checkpoint inhibitor molecule programmed death protein 1 (PD-1) and its programmed death-ligand 1 (PDL-1) play an important role in inhibiting cellular activity as well as the depletion of these cells. In this study, we evaluated PD-1 expression in TCD4+, TCD8+, and CD19+ lymphocytes from SARS-CoV-2-infected patients. A decreased frequency of total lymphocytes and an increased PD-1 expression in TCD4+ and CD19+ lymphocytes were verified in severe/critical COVID-19 patients. In addition, we found a decreased frequency of total monocytes with an increased PD-1 expression on CD14+ monocytes in severe/critical patients in association with the time of infection. Moreover, we observed an increase in sPD-L1 circulant levels associated with the severity of the disease. Overall, these data indicate an important role of the PD-1/PDL-1 axis in COVID-19 and may provide a severity-associated biomarker and therapeutic target during SARS-CoV-2 infection.
