... consistent with trogocytic events, we have described that trogocytosis occurs at the VS from the target to the infected cells, but not in the direction of viral transmission [14]. Of note, trogocytosis, ... HIV transmission. Conversely, the high level of p24 trans- ferred to primary CD4 T cells and their mostly quiescent state are factors that hamper the rapid flow...

... independ- ently of one another. In addition, the model depends cru- cially on the concept that the cessation of proliferation and entry into meiotic arrest is controlled by the stage of development rather ... predom- inant cause of this variance. Finally, we note that the squared root of an inversed moment ratio is mathematically equivalent to the coeffi- cient of va...

In the last section, we point out a contradiction of our results with some arguments of Chimani, Gutwenger, and Mutzel [7]. These contradictions do not disprove their re...
