Quantitative immunophenotyping of peripheral lymphocyte subsets based on flow cytometric analysis of surface markers. (A) Enumeration of absolute numbers of T cells (CD3⁺, CD3⁺ CD4⁺, and CD3⁺ CD8⁺), B cells (CD20⁺) and NK cells (CD3⁻ CD16⁺ CD56⁺) per μl of blood represented as the mean ± standard error of the mean for all animals. (B) The relative distribution of each cell subset is listed as a percentage of total PBMCs. The vertical hashed line indicates the time of intravenous inoculation.
