2. Comparative evaluation of memory T cells in COVID-19 patients and the predictive role of CD4+CD8+ double positive T lymphocytes as a new marker
RESUMO OBJETIVO: A pandemia de COVID-19 tem afetado o mundo todo, constituindo uma ameaça grave para a saúde humana. As células T desempenham um papel crítico na imunidade celular contra infecções virais. Procuramos desvendar a relação entre sub grupos de células T e a severidade da doença. MÉTODOS: Um total de 40 pacientes com COVID-19 foram al

3. Subsets of T lymphocytes in the lesional skin of pityriasis rosea
Abstract: Background: Pityriasis rosea is a common papulosquamous disorder. However, its etiology and pathogenesis remain unclear. Objective: We investigate the types of inflammatory cells infiltrating the lesional skin of pityriasis rosea and demonstrate whether T-cell-mediated immunity is involved in the pathogenesis of this condition or not. Methods: T

4. CYP2B6 516 G>T polymorphism and side effects of the central nervous system in HIV-positive individuals under Efavirenz treatment: Study of a sample from southern Brazil
ABSTRACT This study aimed to identify the 516 G>T polymorphism of the CYP2B6 gene and evaluate its influence on central nervous system (CNS) side effect development in HIV-positive individuals undergoing Efavirenz (EFV) treatment in a population from southern Brazil. Additionally, we performed a survey on the clinical and epidemiological characteristics of o

5. Prolonged lymphocytosis as the first manifestation of Hodgkin-like adult T-cell leukemia/lymphoma
Abstract Hodgkin-like ATLL is a rare variant of adult T-cell leukemia/lymphoma (ATLL), a disease caused by human T-cell lymphotropic virus type-1 (HTLV-1). At admission, a 46-year-old female presented with lymphadenomegaly, lymphocytosis, slight elevation of LDH blood level, and acid-alcohol resistant bacilli in sputum and was being treated for pulmonary tub

6. Granuloma faciale: clinical, morphological and immunohistochemical aspects in a series of 10 patients
Abstract Granuloma faciale is a chronic, benign, cutaneous vasculitis with well-established clinical and morphological patterns, but with an unknown etiology. This study describes clinical and pathologic aspects of patients diagnosed with granuloma faciale. The authors analyzed demographic, clinical, morphological and immunohistochemical data from patients w

7. In situ CUTANEOUS CELLULAR IMMUNE RESPONSE IN DOGS NATURALLY AFFECTED BY VISCERAL LEISHMANIASIS
SUMMARY Thirty-eight dogs naturally affected by visceral leishmaniasis were recruited in Araçatuba, São Paulo State, Brazil - an endemic area for visceral leishmaniasis. The animals were distributed into one of two groups, according to their clinical and laboratory features, as either symptomatic or asymptomatic dogs. Correlations between clinical features

8. T cell receptor signaling pathway is overexpressed in CD4 + T cells from HAM/TSP individuals
ABSTRACT Human T-lymphotropic virus type 1 (HTLV-1) is a human retrovirus related to the chronic neuroinflammatory disease HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). CD4+ T cells activation appears to play a key role on HTLV-1 infection. Here we investigated the expression of genes associated to T cell activation CD3e molecule, epsi

9. Leukocytosis, muscle damage and increased lymphocyte proliferative response after an adventure sprint race
The effect of an adventure sprint race (ASR) on T-cell proliferation, leukocyte count and muscle damage was evaluated. Seven young male runners completed an ASR in the region of Serra do Espinhaço, Brazil. The race induced a strong leukocytosis (6.22±2.04×103 cells/mm3 before vs 14.81±3.53×103 cells/mm3 after the race), marked by a significant increase

10. Papel de linfócitos Th17 durante a infecção experimental por Leishmania infantum/chagasi / Role of Th17 lymphocytes during Leishmania infantum/chagasi infection
Visceral leishmaniasis (LV) is a chronic and potentially fatal disease caused by Leishmania donovani and Leishmania infantum/chagasi. The development of Th1 response is classically associated with protection against these parasites, but recent data also show that there is a positive correlation between the Th17-related cytokines production and the protection

11. Intestinal parasitic infections in HIV/AIDS patients: epidemiological, nutritional and immunological aspects
This study applied a socioeconomic questionnaire designed to evaluate the frequency of intestinal parasites and characterize epidemiological, nutritional, and immunological variables in 105 HIV/AIDS patients - with and without parasitic infections, attending the Day Hospital in Botucatu, UNESP, from 2007 to 2008. Body mass index was calculated and the follow

12. Perfil fenotípico de linfócitos T CD8+ na fase aguda da dengue / Phenotypic profile of CD8+ T cells in acute dengue infection
A dengue é uma doença infecciosa aguda causada pelo vírus DEN do gênero Flavivirus e é transmitida pela picada de um mosquito vetor, principalmente o Aedes aegypti. Existem quatro sorotipos do vírus da dengue (DEN-1, DEN-2, DEN-3 e DEN-4) e sua incidência tem aumentado dramaticamente nos últimos 50 anos, inclusive no Brasil. O objetivo deste trabalho
