immune system
• thymocytes are impaired in a late stage of maturation and show limited clonal deletion to the Mls-1a self-superantigen but not to staphylococcal enterotoxin A
• thymocytes and mature T cells fail to flux calcium to any large extent in response to TCR cross-linking
• IgG2a is consistently elevated by 30-40%
• consistently elevated by 30-40%
• mature T cells fail to flux calcium to any large extent in response to TCR cross-linking
• thymocytes of each single positive phenotype fail to proliferate in response to anti-CD3 and PMA, in contrast with single positive wild-type thymocytes
• proliferation of thymocytes in response to anti-CD3 or anti-Thy-1 cross-linking is substantially compromised, however peripheral T cell activation responses are largely functional
• production of IL-2 by splenic T cells is reduced in response to TCR activation

behavior/neurological
• show impaired spatial learning in Morris water maze test

nervous system
• exhibit an increased number of granule cells in the dentate gyrus
• exhibit undulation of the granule cell layer
• undulation of the pyramidal cell layer in the CA3 region and in the dentate gyrus
• apical dendrites of CA1 pyramidal neurons appear less tightly organized
• exhibit an increased number of pyramidal cells in the CA3 region
• LTP is blunted in the CA1 neurons of hippocampal slices, in both the field EPSP and in the population spike, even though synaptic transmission and two short-term forms of synaptic plasticity, paired-pulse facilitation and post-tetanic

hematopoietic system
• thymocytes are impaired in a late stage of maturation and show limited clonal deletion to the Mls-1a self-superantigen but not to staphylococcal enterotoxin A
• IgG2a is consistently elevated by 30-40%
• consistently elevated by 30-40%
• mature T cells fail to flux calcium to any large extent in response to TCR cross-linking
• thymocytes of each single positive phenotype fail to proliferate in response to anti-CD3 and PMA, in contrast with single positive wild-type thymocytes
• proliferation of thymocytes in response to anti-CD3 or anti-Thy-1 cross-linking is substantially compromised, however peripheral T cell activation responses are largely functional

endocrine/exocrine glands
• proliferation of thymocytes in response to anti-CD3 or anti-Thy-1 cross-linking is substantially compromised, however peripheral T cell activation responses are largely functional

cellular
• thymocytes of each single positive phenotype fail to proliferate in response to anti-CD3 and PMA, in contrast with single positive wild-type thymocytes
