of splenic cell counts, mouse spleens were harvested and the cells
dispersed in media by gentle teasing and then centrifuged at 500g. Cell pellets were resuspended in media and total spleen
cell counts were performed manually using a standard hemocytometer
and light microscopy. Lymphocyte subsets were quantified by flow cytometry
using the following antibody reagents: BV605 rat anti-mouse CD3 clone
17A2 (#564009, BD Biosciences); BV786 rat anti-mouse CD4 clone RM4–5
(#563727, BD Biosciences); BV711 rat anti-mouse CD8a clone 53-6.7
(#100748, BioLegend); PE-Cy7 mouse anti-mouse NK1.1 clone PK136 mouse
(#552878, BD Biosciences); APC rat anti-mouse CD19 clone 1D3 (#550992,
BD Biosciences). Peripheral blood cell counts and spleen white blood
cell counts were determined on a Beckman Coulter Ac.T diff hematology
analyzer.
