Follicular helper T cell in immunity and autoimmunity

Braz. j. med. biol. res; 49 (5), 2016
The traditional concept that effector T helper (Th) responses are mediated by Th1/Th2 cell subtypes has been broadened by the recent demonstration of two new effector T helper cells, the IL-17 producing cells (Th17) and the follicular helper T cells (Tfh). These new subsets have many features in common, ...

CD4+ T cells in aged or thymectomized recipients of allogeneic stem cell transplantations

Biol. Res; 48 (), 2015
BACKGROUND: CD4+CD25highFOXP3+ regulatory T (Treg) cells, which include thymus-derived and peripherally induced cells, play a central role in immune regulation, and are therefore crucial to prevent graft-versus-host disease (GVHD). The increasing use of allogeneic hematopoietic stem cell transplantation ...

Correlación entre multitest-CMI in vivo v/s determinación de subpoblaciones de linfocitos T in vitro
Correlation between in vivo multitest-CMI versus peripheral blood T-lymphocytes determination in vitro

Para la evaluación de la inmunidad mediada por células (CMI) existen técnicas de cuantificación y funcionales, por ejemplo el multitest-CMI (MT-CMI). La CMI es función del linfocito T CD4(+) asumiendo la intensidad de la respuesta proporcional al número de LT-CD4(+) circulantes. Se analizaron deter...
