MALT1 and B-cell non-Hodgkin lymphoma: These transgenic mice expressing human CEACAM3 were crossed with mice deficient in key phagocytic (Rac2), inflammatory signalling (B cell lymphoma/leukaemia 10 [Bcl10]) and Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (Malt1), to study processes downstream of CEACAM3 in the anti-gonococcal responses of neutrophils [113].
