immune system
• CD4+ T cells exhibit a smaller homeostatic proliferation response than in controls
• however, T cells are capable of proliferating in vivo in response to antigenic stimulation
• CD4+ T cells exhibit a smaller homeostatic proliferation response than in controls
• TH2-mediated IL-4 secretion is impaired but TH1 responses are normal
• TH2-mediated IL-4 secretion is impaired but TH1 responses are normal
