CD11R3 antibody | 2F4/11
Mouse anti Porcine CD11R3 antibody, clone 2F4/11 (MCA2309) employed in the measurement of CD11R3 expression as a measure of neutrophil activation in a porcine model of metabolic syndrome by flow cytometry.
Image caption:
Systemic neutrophil activation can be evaluated by acute changes in CD11R3 expression and the percent circulating neutrophil population that is resistant to apoptosis in vitro. CD11R3 expression is increased acutely with neutrophil activation. With SCD exposure, CD11R3 expression decreased (a, n-6*, p=0.033). During the activated state neutrophil apoptosis is delayed. In these MetS animals, prior to SCD treatment, 34% of neutrophils are activated (resistant to apoptosis), while in healthy animals, less than 10% of circulating neutrophils are expected to be resistant to apoptosis. Analysis of apoptosis, before and after treatments, showed SCD Rx to move the neutrophil population to a less activated state, thus shifting toward naïve percentages of neutrophils resistant to apoptosis (b, n=9, p=0.023). For CD11R3 expression, only 2 of the 3 SCD Rx courses with three 6-hour treatments each were included in the analysis (n=6) due to an unanticipated analytic procedural complication.

Mouse anti Pig CD11R3, clone 2F4/11 recognizes porcine CD11R3, a ~155 kDa cell surface glycoprotein, member of the alpha integrin family. Mouse anti Pig CD11R3, clone 2F4/11 was clustered as CD11R3 at the Third International Workshop on Swine Leukocyte Differentiation Antigens (Haverson et al. 2001). CD11R3 has a similar expression pattern to the human CD11b marker, being expressed on granulocytes, monocytes and alveolar macrophages, but not on lymphocytes, eythrocytes or platelets (Dominguez et al. 2001).
Mouse anti Pig CD11R3, clone 2F4/11 is reported to block phagocytosis of complement-opsonized zymosan particles by polymorphonuclear granulocytes and alveolar macrophages (Bullido et al. 1996).
