Down-regulation of Th1 type of response in early human American cutaneous leishmaniasis.
Th1 and Th2 cells promote different inflammatory reactions.
It has been demonstrated that Th1 differentiation is influenced by STAT1, STAT4 and T-bet and Th2 differentiation is influenced by STAT6, c-maf and GATA-3.
Thus, ACAID could be adapted to induce tolerogenic immunotherapy in humans in cases of Th1 or Th2-induced inflammation.
Algunos estudios en ratones, demostraron que la deficiencia de retinol aumenta, durante la infeccion, la produccion de las citocinas que favorecen la respuesta TH1, reflejada en una sobreproduccion de interferon gamma (IFN-[alfa]) y una debil respuesta de anticuerpos, a diferencia de los ratones sin deficiencia en quienes prima la respuesta TH2.
Our results indicate that tuberculosis activates the Th1 immune response, and also that there is a positive correlation between PBMC-IG and some clinical and laboratory variables.
IL-12 is a key cytokine in the activation of TH1 cells and the subsequent production of IFN[gamma], an important activator of macrophages and dendritic cells.
6) On antigenic stimulation, naive Th cells differentiate into distinct Th1 or Th2 functional subgroups.
First, worm burdens were not quantified and lighter worm burdens may not cause the immune activation or Th1 and Th2 response that is significant enough to affect HIV replication.
They then mature into either Th1 or Th2 helper cells, and both the functions of those helper cells, as well as their "residence" in the body, differ substantively.
The researchers review posttranslational modifications of self-antigens, histo-blood group antigens as autoantigens, differential regulation of the IL-10 gene in Th1 and Th2 T cells, long-lived plasma cells, and a new automated fluorescence PR3 and MPO-ANCA immunoassay.
