“…γδ T cells is one of three lymphocyte lineages and only constitutes a very small proportion of lymphocytes as compared to the conventional αβ T cells and B cells (84). But γδ T cells have various immune functions and have been suggested to play roles in infectious diseases including leprosy (84,85). In the case of leprosy, at least two different roles of γδ T cells have been suggested, namely, contributing to leprosy reactions and immunosuppression.…”

“…Some studies have shown the potential of Treg-cell depletion to augment antitumor immune responses ( 59 ) and infectious disease outcome ( 60 ) and have indicated that Treg-mediated T-cell suppression is an important mechanism by which pathogens evade immune responses ( 39 , 53 ). In leprosy, an increased frequency of Treg cells was observed, and those lymphocyte subsets seem to contribute to pathogen persistence ( 13 , 31 33 , 61 , 62 ). Our group assessed the suppressor features of Treg cells isolated from leprosy patients (Figure 1 ).…”

“…The FoxP3 + Treg phenotype seems to be reverted into Th17, exploring the signaling through IL-12 and IL-23 ( 31 ). Th17 and Treg cells are new players associated with immunopathology in leprosy and its reactions ( 62 ). In this context, the ideal treatment for LL patients seems to require modulation of the T lymphocytes subsets to expand Th17 lymphocytes and control Treg cells, favoring the cellular immune response ( 5 , 33 ).…”

“…Existem três subtipos distintos de respostas imunes dos linf T CD4 + , a saber, resposta tipo Th-1,Th-2 ou Th-17, que estão envolvidas na defesa de diferentes tipos de infecções e de lesão tecidual. As características que os definem e os distinguem são as citocinas produzidas, os fatores de transcrição que expressam e as alterações epigenéticas nos loci genéticos de cada citocina (37) (Figura 6).…”

“…Os indivíduos saudáveis apresentaram mediana de sjTREC maior do que qualquer grupo de pacientes (p< 0,0001) e o grupo de pacientes com doença mieloide apresentou mediana de sjTREC mais elevada do que os pacientes com MM (p= 0,013) (Figura 32) (Tabela 7). Quantificação de sjTREC de acordo o tipo de doença prévia ao TCTH (n= 165)A média de idade por grupo de pacientes foi: 39 anos (IC 95%: 36-43) para indivíduos saudáveis, 52 anos (IC 95%: 49-54) para MM, 45 anos (IC 95%:[38][39][40][41][42][43][44][45][46][47][48][49][50][51][52] para linfomas, 39 anos (IC 95%: 36-42) para doenças mieloides e 33 anos (IC 95%:[29][30][31][32][33][34][35][36][37] para LLA. Entre os indivíduos saudáveis e os grupos de doenças, existe diferença de média de idades em relação à LLA e ao MM (respectivamente, p= 0,022 e p< 0,001).Particularmente entre os pacientes com doença mieloide, também foi observada semelhante diferença de idades em relação à LLA e ao MM (p< 0,001).A mediana de sjTREC encontrada na população foi de 607 sjTREC cópias/µg DNA.…”
