Abstract
ABSTRACT
Respiratory challenge with the murine gammaherpesvirus 68 (γHV-68) results in productive infection of the lung, the establishment of latency in B lymphocytes and other cell types, transient splenomegaly, and prolonged clonal expansion of activated CD8
+
CD62L
lo
T cells, particularly a Vβ4
+
CD8
+
population that is found in mice with different major histocompatibility complex (MHC) haplotypes. Aspects of the CD8
+
-T-cell response are substantially modified in mice that lack B cells, CD4
+
T cells, or the CD40 ligand (CD40L). The B-cell-deficient mice show no increase in Vβ4
+
CD8
+
T cells. Similar abrogation of the Vβ4
+
CD8
+
response is seen following antibody-mediated depletion of the CD4
+
subset, through the numbers of CD8
+
CD62L
lo
cells are still significantly elevated. Virus-specific CD4
+
-T-cell frequencies are minimal in the CD40L
−/−
mice, and the Vβ4
+
CD8
+
population remains unexpanded. Apparently B-cell–CD4
+
-T-cell interactions play a part in the γHV-68 induction of both splenomegaly and non-MHC-restricted Vβ4
+
CD8
+
-T-cell expansion.
