Alterations in B1-B cell populations in the omentum and peritoneal exudate following MHV68 infection.

<p>Cells from the omentum and peritoneal cavity (PECs) were isolated at the indicated times post-intraperitoneal infection and analyzed by flow cytometry. Live cells were gated on CD3⁻CD19⁺CD11b⁺ cells and B1-a and B1-b populations discriminated by CD5 expression. A) Representative flow plots and B–D) compiled data from experimental groups of mice represented as line graphs for B1a B cells (B), B1b B cells (C), and total B1 B cell (D) frequencies. Squares, [cells from] peritoneal cavity; Circles, [cells from] omentum; Open symbols, mock-infected; filled symbols, MHV68-infected.
