6. Post-LFA-1 activation, MK2 inducibly associates with both hnRNPC and HuR, resulting in the dissociation of HuR from hnRNPs C, H1 and K. Freed from the three hnRNPs, HuR translocates from the nucleus to the cytoplasm, and mediates the stabilization of labile cytokine transcripts. Modulation of T cell cytokine mRNA half-life is an intricate process that is negatively regulated by hnRNPs C, H1 and K and requires MK2.

7. CD18-mediated adhesion of extracellular vesicles is a prerequisite for their proinflammatory activity.

8. The LFA-1-ICAM-1 orientation described here with ICAM-1 pointing anti-parallel to the LFA-1 beta-subunit leg is the same orientation that would be stabilized by tensile force transmitted between the ligand and the actin cytoskeleton and is consistent with the cytoskeletal force model of integrin activation.

13. on tumour-infiltrating T-lymphocytes, galectin prevents the formation of a functional secretory synapse by preventing optimal LFA-1 triggering

14. exploration of the underlying mechanism demonstrated that ICAM3 not only binds to LFA-1 with its extracellular domain and structure protein ERM but also to lamellipodia with its intracellular domain which causes a tension that pulls cells apart (metastasis).

15. vesicle-associated RhoB is a regulator of the Rab11-mediated recycling of LFA-1 to the cell surface, an event that is necessary for T lymphocyte motility.

16. alphaMbeta2 uses its alphaI domain to bind iC3b at the thioester domain and simultaneously interacts through a region near the alphaM beta-propeller and beta2 betaI domain with a region of the C3c moiety near the C345C domain.

17. The ITGB2 variant rs2230531 was examined in an independent cohort of Tasmanian patients with hematologic malignancies (HM) to see if its presence correlated with chronic lymphocytic leukemia. The variant was found in several lymphoid and myeloid HMs, so if contributes to the risk of HM, it does so broadly across HM subtypes in this population.

18. Data suggest that the residue volume at phenylalanine (Phe) in alpha1-helix is critical for alpha(L)/beta(2) integrin (CD49a/CD18) activation and binding with soluble/immobilized ICAM1 (intercellular cell adhesion molecule 1).

19. an integrated strategy of whole genome and transcriptome analysis enabled identification of LB-ITGB2-1 as HLA-B*15:01-restricted MiHAs encoded by an alternative transcript. The alternative ITGB2 transcript was shown to be expressed in leukemic cells of different origins.

20. Neutrophil rolling over E-selectin at precise shear stress transmits tension and catch-bond formation with L-selectin via sLe(x), resulting in focal clusters that deliver a distinct signal to upshift beta2-integrins to a high-affinity state. Rivipansel effectively blocked formation of selectin catch-bonds, revealing a novel mechanotransduction circuit

4. Neutrophil CD11b/CD18 limits pathology in influenza-induced, T cell-mediated disease.

5. We show that during T cell migration within lymphatic organs the contributions of the integrin LFA-1 and the chemokine receptor CCR7 are complementary rather than positioned in a linear pathway, as they are during leukocyte extravasation from the blood vasculature

6. Post-LFA-1 activation, MK2 inducibly associates with both hnRNPC and HuR, resulting in the dissociation of HuR from hnRNPs C, H1 and K. Freed from the three hnRNPs, HuR translocates from the nucleus to the cytoplasm, and mediates the stabilization of labile cytokine transcripts. Modulation of T cell cytokine mRNA half-life is an intricate process that is negatively regulated by hnRNPs C, H1 and K and requires MK2.

7. LFA-1 dominates polymorphonuclear leukocyte (PMN) adhesion on ICAM-1 and ICAM-2, while Mac-1 mediates PMN adhesion on RAGE, JAM-A, and JAM-C

8. CD18(-/-) leukocytes extravasated later than WT leukocytes. However, once extravasated, CD18(-/-) leukocytes transmigrated more rapidly than their WT counterparts. These results suggest that, although CD18 facilitates efficient extravasation, outside of the vessel CD18 interaction with the extracellular matrix, it reduced transmigration velocity.
