One part that I didn't quite understand is how does CCR5 antagonism yield an increase in CCL4?



The interaction that signals the activated T cells is CCL4-CCR5. The way I understand it, quick-and-dirty is that (VX) will antagonize the RANTES-CCR5 axis increasing the CCL4-CCR5 interactions. This is turn will restore homeostasis meaning more CCL4

From Agrestis's paper,

https://www.sciencedirect.com/science/article...034#bbib40

In a landmark study, Chua et al described lung epithelium and immune cell interactions and concluded that pharmacological inhibition of either the C–C chemokine receptor type 1 (CCR1) or CCR5 pathways may restore immune homeostasis

Chua et-al paper, depicts in more detail how this is concluded.

And I also didn't understand Dr. BP's statement "a reduction on the CCL4-mediated recruitment of activated T cells is proposed". I thought the goal was to increase CCL4 and thus increase the recruitment of activated T cells???



I believe he is saying that, mainly, the reduction of CCL4-mediated recruitment is what is producing the LH symptoms. If there were more recruitment of T activated cells the virus would be cleared as the required inflammatory response is already present (elevated IFN-a).
