Genes involved in lymphocyte development and function exhibiting significant difference in expression between resistant and susceptible birds.

Genes which are involved in lymphocyte differentiation, migration and activation are separated into those which are more closely associated with B cells and T cells. Genes are ordered according to fold-difference and specified as displaying either increased (+) or decreased (−) expression in resistant relative to susceptible birds. There is clear evidence for increased B cell and T cell development and activation in resistant birds, with most genes demonstrating greater expression (+).
