3. β-Glucan of Candida albicans Cell Wall Extract Inhibits Salmonella Typhimurium Colonization by Potentiating Cellular Immunity (CD8 + and CD4 + T Cells)
Abstract INTRODUCTION: Antimicrobial resistance has been reported in the drugs used for the treatment of typhoid fever. The immunomodulatory substance β-glucan can be used as an alternative therapy as it potentiates host immunity. The aims of this study are to observe the effect of Candida albicans cell wall (CCW) extract towards host immunity (TCD8+ and T

4. Increased peripheral blood TCD4+ counts and serum SP-D levels in patients with chronic paracoccidioidomycosis, during and after antifungal therapy
BACKGROUND The main clinical forms of paracoccidioidomycosis (PCM) are the acute/subacute form (AF) and the chronic form (CF), and they both display considerable clinical variability. The immune responses of PCM patients, during and after treatment, remain neglected, mainly in the case of CF patients, due to the high prevalence of pulmonary sequelae. OBJEC

5. Anti-CD3 Antibody Ameliorates Transfusion-Associated Graft-Versus-Host Disease in a Chemotherapy-Based Mouse Model With Busulfan and Fludarabine
ABSTRACT To establish a transfusion-associated graft-versus-host disease (TA-GVHD) mouse model with busulfan and fludarabine for effective treatment evaluation. BALB/c (H-2d) mice were injected with busulfan (15 mg/kg) and fludarabine (30 mg/kg) twice a day for 4 days. The mice were transfused with 106 T cell-depleted bone marrow (TCD-BM )and cells in differ

6. Bacillary angiomatosis with bone invasion
Abstract Bacillary angiomatosis is an infection determined by Bartonella henselae and B. quintana, rare and prevalent in patients with acquired immunodeficiency syndrome. We describe a case of a patient with AIDS and TCD4+ cells equal to 9/mm3, showing reddish-violet papular and nodular lesions, disseminated over the skin, most on the back of the right hand

7. Opportunistic infections among individuals with HIV-1/AIDS in the highly active antiretroviral therapy era at a Quaternary Level Care Teaching Hospital
INTRODUCTION : In this study, clinical-laboratory and epidemiological characteristics are described for a group of 700 individuals with HIV (human immunodeficiency virus)/AIDS (acquired immunodeficiency syndrome) in the ART (antiretroviral therapy) era at a teaching hospital that provides a quaternary level of care, with an emphasis on opportunistic infecti

8. T regulatory cells (TREG)(TCD4+CD25+FOXP3+) distribution in the different clinical forms of leprosy and reactional states
BACKGROUND: Leprosy is characterized histologically by a spectrum of different granulomatous skin lesions, reflecting patients' immune responses to Mycobacterium leprae. Although CD4+CD25+ FoxP3+ T regulatory cells are pivotal in the immuneregulation, presence, frequency, an

9. Pharmacoeconomic analysis of clinical pharmacy in HIV-positive patients / Análise farmacoeconômica da farmácia clínica em pacientes HIV positivo = : Pharmacoeconomic analysis of clinical pharmacy in HIV-positive patients
Studies demonstrate that clinical pharmacy with HIV-positive patients can lead to positive clinical results. However, few studies evaluate its economic impact. The objective of this study is to verify the economic impact of pharmaceutical care with HIV-positive patients. A prospective controlled study with systematic sampling by quota with controls paired by

10. Estudo molecular da via extrínseca da apoptose em indivíduos com imunodeficiência comum variável. / Molecular study of extrinsec apoptosis pathway in patients with Common Variable Immunodeficiency.
Common Variable Immunodeficiency (CVID) is is characterized by low immunoglobulins levels with susceptibility to infections. We have analyzed T cell distribution and spontaneous apoptosis in peripheral blood of CVID, as well as gene expression of several molecules involved in apoptosis, including death receptors, ligands, adapters, regulatory and anti-apotot

11. 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

12. Whole-body vibration decreases the proliferativeb response of TCD4+ cells in elderly individuals with knee osteoarthritis
The aim of this study was to investigate the effect of adding whole-body vibration (WBV; frequency = 35 to 40 Hz; amplitude = 4 mm) to squat training on the T-cell proliferative response of elderly patients with osteoarthritis (OA) of the knee. This study was a randomized controlled trial in which the selected variables were assessed before and after 12 week
