immune system
• CD4+ T cells isolated from OVA-immunized mice show less proliferation in response to secondary antigen exposure than wild-type T cells
• splenocytes from null mice have a lower proliferative response to secondary exposure to OVA than do wild-type
• knockouts have lower levels of IgE and IgG2 than wild-type mice
• knockouts sensitized to OVA and challenged with OVA do not show increased levels of cytokines like control mice do
• knockout mice immunized 2x with OVA have much fewer cellular infiltrates and very little goblet cell hyperplasia in the bronchi when challenged with OVA compared wild-type controls challenged with OVA

respiratory system
• knockout mice immunized 2x with OVA have much fewer cellular infiltrates and very little goblet cell hyperplasia in the bronchi when challenged with OVA compared wild-type controls challenged with OVA

hematopoietic system

cellular
• CD4+ T cells isolated from OVA-immunized mice show less proliferation in response to secondary antigen exposure than wild-type T cells
