immune system
• osteoclasts formation in response to RANKL stimulation is reduced
• proliferation in response to CD40L, LPS, or BCR ligation is significantly reduced
• double positive, double negative, and CD4 single positive cells are significantly increased in number while the number of CD8 positive cells is unchanged
• thymus is enlarged in young homozygous null mice compared with wild-type
• with age the thymus becomes smaller in size and cellularity compared with age-matched wild-type
• an increased proportion of the CD4 single positive cells had the appearance of recent thymic emigrants (CD69-, CD62L+), suggesting that thymic export may be impaired
• does not correlate with an increase in splenocyte number
• enlargement becomes more pronounced with age
• isotype switching in vitro in response to CD40L, LPS, or BCR ligation is reduced
• number of transitional stage 2 B cells is profoundly reduced
• number of transitional stage 1 B cells is significantly increased
