Hi Hal,
I dont think Thrombopoietin has much effect here, I did get sucked into TPO effects initially but my WBC responses put that to rest.
Answer lies more in the Treg cells and cytokine signalling side with inflammation playing a major role.
What I believe is happening is as IL-10 slowly increases and up- regulates Treg cells.
More Treg cells go up we see less killer t cells.
So as time goes on Treg and Killer T balances out with platelets going up or atleast finds an equilibrium.
Interleukin-10 signaling in regulatory T cells is required for suppression of Th17 cell-mediated inflammation
