Signalling through Src family kinase isoforms is not redundant in models of thrombo-inflammatory vascular disease.

ABSTRACT: The Src family kinases (SFK) are a group of signalling molecules with important regulatory functions in inflammation and haemostasis. Leucocytes and platelets express multiple isoforms of the SFKs. Previous studies used broad-spectrum pharmacological inhibitors, or murine models deficient in multiple SFK isoforms, to demonstrate the functional consequences of deficiencies in SFK signalling. Here, we hypothesized that individual SFK operate in a non-redundant fashion in the thrombo-inflammatory recruitment of monocyte during atherosclerosis. Using in vitro adhesion assays and single SFK knockout mice crossed with the ApoE^-/- model of atherosclerosis, we find that SFK signalling regulates platelet-dependent recruitment of monocytes. However, loss of a single SFK, Fgr or Lyn, reduc
