Immune system-related pathology is common in ataxiatelangiectasia (A-T) patients and mice that lack the protein kinase, A-T mutated (ATM). However, it has not been studied how ATM influences immune responses to a viral infection. Using the lymphocytic choriomeningitis virus (LCMV) infection model, we show that ATM-/- mice, despite having fewer naïve CD8+ T cells, effectively clear the virus. However, aberrant CD8+ T-cell responses are observed, including defective expansion and contraction,...[Show more]
