Figure 7From: The role of TGF-β signaling and apoptosis in innate and adaptive immunity in zebrafish: a systems biology approach Protein interactions of caspase 2 in primary infection. Caspase 2 was identified to be a hub protein during both primary and secondary infection. Bcl2, an anti-apoptotic protein, did only interact with Casp2 during primary infection.Back to article page
