    Cathelicidin protects mice from Rhabdomyolysis-induced Acute Kidney Injury
    (2021) SILVA, Beatriz Helena Cermaria Soares da; ARIGA, Suely Kubo; BARBEIRO, Hermes Vieira; VOLPINI, Rildo Aparecido; BARBEIRO, Denise Frediani; SEGURO, Antonio Carlos; SILVA, Fabiano Pinheiro da
    Background: Cathelicidins are ancient and well-conserved antimicrobial peptides (AMPs) with intriguing immunomodulatory properties in both infectious and non-infectious inflammatory diseases. In addition to direct antimicrobial activity, cathelicidins also participate in several signaling pathways inducing both pro-inflammatory and anti-inflammatory effects. Acute kidney injury (AKI) is common in critically ill patients and is associated with high mortality and morbidity. Rhabdomyolysis is a major trigger of AKI. Objectives: Here, we investigated the role of cathelicidins in non-infectious Acute kidney Injury (AKI). Method: Using an experimental model of rhabdomyolysis, we induced AKI in wild-type and cathelicidin-related AMP knockout (CRAMP(-/-)) mice. Results: We previously demonstrated that CRAMP(-/-) mice, as opposed wild-type mice, are protected from AKI during sepsis induced by cecal ligation and puncture. Conversely, in the current study, we show that CRAMP(-/-) mice are more susceptible to the rhabdomyolysis model of AKI. A more in-depth investigation of wild-type and CRAMP(-/-) mice revealed important differences in the levels of several inflammatory mediators. Conclusion: Cathelicidins can induce a varied and even opposing repertoire of immune-inflammatory responses depending on the subjacent disease and the cellular context.

    Hypertonic solution-induced preconditioning reduces inflammation and mortality rate
    (2019) PIMENTEL, Rosangela Nascimento; PETRONI, Ricardo Costa; BARBEIRO, Hermes Vieira; BARBEIRO, Denise Frediani; ANDRADE, Mariana Macedo; ARIGA, Suely Kumini; SORIANO, Francisco Garcia
    BackgroundDysregulated inflammatory response is common cause of organ damage in critical care patients. Preconditioning/tolerance is a strategy to prevent exacerbated inflammation. The aim of this study is to analyze hypertonic saline 7.5% as a potential inducer of preconditioning that protect from a lethal dose of LPS and modulates systemic inflammatory profile in mice.MethodsMale Balb/C mice received intravenous (i.v.) injections of Hypertonic solution (NaCl 7.5%) (0.8ml) for 3days, on day 8th was challenged with LPS 15mg/kg. Controls with Saline 0.9%, urea and sorbitol were performed. Microarray of mRNA expression was analyzed from HS versus saline from macrophages to identified the pathways activated by HS.ResultsHS preconditioning reduced mortality after LPS injection as well reduced the cytokines release in plasma of the animals challenged by LPS. In order to check how HS induces a preconditioning state we measured plasma cytokines after each HS infusion. Repeated HS injections induced a state of preconditioning that reprograms the inflammatory response, resulting in reduced inflammatory cytokine production. A microarray of mRNA demonstrated that Hypertonic solution increased the expression of several genes in special Mapkbp1 and Atf3.Conclusionhypertonic solution induces preconditioning/tolerance reducing mortality and inflammatory response after LPS challenge.

    Effect of the ketamine/xylazine anesthetic on the auditory brainstem response of adult gerbils
    (2012) LIMA, J. P.; ARIGA, S.; VELASCO, I.; SCHOCHAT, E.
    The auditory brainstem response (ABR) is a test widely used to assess the integrity of the brain stem. Although it is considered to be an auditory-evoked potential that is influenced by the physical characteristics of the stimulus, such as rate, polarity and type of stimulus, it may also be influenced by the change in several parameters. The use of anesthetics may adversely influence the value of the ABR wave latency. One of the anesthetics used for ABR assessment, especially in animal research, is the ketamine/xylazine combination. Our objective was to determine the influence of the ketamine/xylazine anesthetic on the ABR latency values in adult gerbils. The ABRs of 12 adult gerbils injected with the anesthetic were collected on three consecutive days, or a total of six collections, namely: pre-collection and A, B, C, D, and E collections. Before each collection the gerbil was injected with a dose of ketamine (100 mg/kg)/xylazine (4 mg/kg). For the capture of the ABR, 2000 click stimuli were used with rarefaction polarity and 13 stimuli per second, 80 dBnHL intensity and in-ear phones. A statistically significant difference was observed in the latency of the V wave in the ABR of gerbils in the C and D collections compared to the pre-, A and E collections, and no difference was observed between the pre-, A, B, and E collections. We conclude that the use of ketamine/xylazine increases the latency of the V wave of the ABR after several doses injected into adult gerbils; thus, clinicians should consider the use of this substance in the assessment of ABR.

    Lower peripheral blood Toll-like receptor 3 expression is associated with an unfavorable outcome in severe COVID-19 patients
    (2021) MENEZES, Maria Clara Saad; VEIGA, Alicia Dudy Muller; LIMA, Thais Martins de; ARIGA, Suely Kunimi Kubo; BARBEIRO, Hermes Vieira; MOREIRA, Claudia de Lucena; PINTO, Agnes Araujo Sardinha; BRANDAO, Rodrigo Antonio; MARCHINI, Julio Flavio; ALENCAR, Julio Cesar; MARINO, Lucas Oliveira; GOMEZ, Luz Marina; CAMARA, Niels Olsen Saraiva; SOUZA, Heraldo P.
    The role of innate immunity in COVID-19 is not completely understood. Therefore, this study explored the impact of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection on the expression of Pattern Recognition Receptors (PRRs) in peripheral blood cells and their correlated cytokines. Seventy-nine patients with severe COVID-19 on admission, according to World Health Organization (WHO) classification, were divided into two groups: patients who needed mechanical ventilation and/or deceased (SEVERE, n=50) and patients who used supplementary oxygen but not mechanical ventilation and survived (MILD, n=29); a control group (CONTROL, n=17) was also enrolled. In the peripheral blood, gene expression (mRNA) of Toll-like receptors (TLRs) 3, 4, 7, 8, and 9, retinoic-acid inducible gene I (RIGI), NOD-like receptor family pyrin domain containing 3 (NLRP3), interferon alpha (IFN-alpha), interferon beta (IFN-beta), interferon gamma (IFN-gamma), interferon lambda (IFN-lambda), pro-interleukin(IL)-1 beta (pro-IL-1 beta), and IL-18 was determined on admission, between 5-9 days, and between 10-15 days. Circulating cytokines in plasma were also measured. When compared to the COVID-19 MILD group, the COVID-19 SEVERE group had lower expression of TLR3 and overexpression of TLR4.
