CD8A and infection: The expression of galectin-3 by polyclonal CD8+ T cells induced during γ-HV infection in the spleen is shown in Figure 2C. We also measured expression of galectin-3 protein in adoptively transferred TN cells and in endogenous CD8+ T cells that expanded in response to MHV68 infection in recipient congenic (CD45.1) mice (Figure 2D).
