RAC2 mouse Rac2 - neutrophils
-
Neutrophils display significant defects in chemotaxis, in shear-dependent L-selectin-mediated capture on the endothelial substrate Glycam-1 and in both F-actin generation and p38 and unexpected p42/p44 MAP kinase activation induced by chemoattractants. Superoxide production by bone marrow neutrophils was also significantly reduced. completed

Roberts et al.
RAC2 mouse Rac2 - T cells
-
Proliferation was reduced in Rac2(-/-) T cells upon stimulation with either plate-bound anti-CD3 or T cell receptor-specific antigen and was accompanied by decreased activation of mitogen activated protein kinase extracellular signal-regulated kinase (ERK) 1/2 and p38 as well as reduced Ca (2)+ mobilization. TCR stimulation-induced actin polymerization was reduced and there were significant phenotypic similarities with Vav (-/-) cells implication Rac2 as a downstream mediator of Vav signaling. completed

Mice show baseline neutrophilia, reduced inflammatory peritoneal exudate formation and increased mortality when challenged with Aspergillus fumigatus. completed

For mice and biosensors, a public database is not available and therefore we have attempted to generate a migration related list for your convenience.
