    ..Finally, we consider future directions for the study of Tfh and offer perspective on factors that could be modulated to enhance Tfh function in the context of prophylactic vaccination. ..
  3. Moysi E, Estes J, Petrovas C. Novel Imaging Methods for Analysis of Tissue Resident Cells in HIV/SIV. Curr HIV/AIDS Rep. 2016;13:38-43 pubmed publisher

    ..Our results indicate that CD8 T cells with potent cytolytic activity are recruited to GCs during HIV infection and, if appropriately redirected to kill HIV-infected cells, could be an effective component of an HIV cure strategy. ..

    ..Therefore, chronic SIV does not disturb the ability of TFH cells to help B cell maturation and production of SIV-specific immunoglobulins. ..
  7. Dimopoulos Y, Moysi E, Petrovas C. The Lymph Node in HIV Pathogenesis. Curr HIV/AIDS Rep. 2017;14:133-140 pubmed publisher
