Enumeration of anti-viral CD8(+) T cells to make comparisons between mice, viruses and vaccines is a frequently used approach, but controversy persists as to the most appropriate methods. Use of peptide-MHC tetramers (or variants) and intracellular staining for cytokines, in particular IFNγ, after a short ex vivo stimulation are now common, as are a variety(More)
Efficient infection control requires potent T-cell responses at sites of pathogen replication. However, the regulation of T-cell effector function in situ remains poorly understood. Here, we show key differences in the regulation of effector activity between CD4+ and CD8+ T-cells during skin infection with HSV-1. IFN-γ-producing CD4+ T cells disseminated(More)
DOCK8 deficiency in humans and mice leads to multiple defects in immune cell numbers and function. Patients with this immunodeficiency have a high morbidity and mortality, and are distinguished by chronic cutaneous viral infections, including those caused by herpes simplex virus (HSV). The underlying mechanism of the specific susceptibility to these chronic(More)
