Early characterization of Sn expressed on macrophages identified it as a lymphocyte adhesion molecule that binds sialic acid conjugates on T cells [12], specifically CD43 [40].
On a live lymphocyte gate, the decrease of CFSE label in the CD3+ T cell population was studied (Fig. 4B).
Cells were analyzed on a FACSCalibur (BD Immunocytometry Systems) using a lymphocyte live gate.
Whilst the effect of a cytokine on one lymphocyte subset in SS can be discerned, it has become a challenge to understand how the interaction between several interconnected networks of cytokines impact on so many different cell populations.
As most of the intracellular infections, the immune response to control infection depends primarily on a Th1 lymphocytes outbreak [ 8].
Flow cytometric studies demonstrated that BM had a deleterious effect on all lymphocyte subsets, but most prominently on B cells.
Cells were initially gated to remove doublets, followed by a lymphocytes gate on forward scatter area versus side scatter area.
Lymphocytes from the digested tissue were isolated on a density gradient (Lymphocyte separation medium, MP Biomedicals, Ohio).
Accordingly, to begin to address how ageing influences immunity, a focus on lymphocyte biology seems a good starting point.
A day later, I told Rozalind the devastating news and, based on a T-4 lymphocyte count of 450, that the H.I.V. had already weakened her immune system and explained the large wart.
