Background Increasing evidence suggests an unexpected potential for non-neutralizing antibodies to prevent HIV infection. Consequently, identification of functional linear B-cell epitopes for HIV are important for developing preventative and therapeutic strategies. We therefore explored the role of antigen-specific immune responses in controlling plasma viremia in SIV infected rhesus macaques. Methods...
Transforming growth factor-β1 (TGF-β1) is an important immunoregulatory cytokine that plays an obligate role in regulating T-cell functions. Here, we demonstrated the role of TGF-β1 in regulating the survival of intestinal epithelial cells (ECs) in rhesus colon explant cultures using either anti-TGF-β1 antibody or recombinant TGF-β1 proteins. Neutralization of endogenous TGF-β1 using anti-TGF-β1 antibodies...
Interleukin-10 (IL-10) is an important immunomodulatory cytokine that plays an obligate role in regulating inflammatory responses. Here we demonstrated the role of IL-10 in regulating crypts length and breadth as well as maintaining the survival of epithelial cells using rhesus colon explant cultures. Anti-IL-10 antibody treatment of colon explant cultures induced increased production of inflammatory...
