Moieties of Complement iC3b Recognized by the I-domain of Integrin αXβ2.

Mol Cells 2020 12;43(12):1023-1034

Division of Science Education, Kangwon National University, Chuncheon 24341, Korea.

Complement fragment iC3b serves as a major opsonin for facilitating phagocytosis via its interaction with complement receptors CR3 and CR4, also known by their leukocyte integrin family names, αMβ2 and αXβ2, respectively. Although there is general agreement that iC3b binds to the αM and αX I-domains of the respective β2-integrins, much less is known regarding the regions of iC3b contributing to the αX I-domain binding. In this study, using recombinant αX I-domain, as well as recombinant fragments of iC3b as candidate binding partners, we have identified two distinct binding moieties of iC3b for the αX I-domain.

The hexosamine biosynthesis pathway is a targetable liability in KRAS/LKB1 mutant lung cancer.

Nat Metab 2020 12 30;2(12):1401-1412. Epub 2020 Nov 30.

Children's Medical Center Research Institute, UT Southwestern Medical Center, Dallas, TX, USA.

In non-small-cell lung cancer (NSCLC), concurrent mutations in the oncogene KRAS and the tumour suppressor STK11 (also known as LKB1) encoding the kinase LKB1 result in aggressive tumours prone to metastasis but with liabilities arising from reprogrammed metabolism. We previously demonstrated perturbed nitrogen metabolism and addiction to an unconventional pathway of pyrimidine synthesis in KRAS/LKB1 co-mutant cancer cells. To gain broader insight into metabolic reprogramming in NSCLC, we analysed tumour metabolomes in a series of genetically engineered mouse models with oncogenic KRAS combined with mutations in LKB1 or p53.

Calpain-2 as a therapeutic target in repeated concussion-induced neuropathy and behavioral impairment.

Sci Adv 2020 Jul 1;6(27). Epub 2020 Jul 1.

Graduate College of Biomedical Sciences, Western University of Health Sciences, Pomona, CA 91766, USA.

Repeated concussion represents a serious health problem as it can result in various brain pathologies, ranging from minor focal tissue injury to severe chronic traumatic encephalopathy. The calcium-dependent protease, calpain, participates in the development of neurodegeneration following concussion, but there is no information regarding the relative contribution of calpain-1 and calpain-2, the major calpain isoforms in the brain. We used a mouse model of repeated concussions, which reproduces most of the behavioral and neuropathological features of the human condition, to address this issue. Read More

The Role of Dendritic Cells in TB and HIV Infection.

J Clin Med 2020 Aug 17;9(8). Epub 2020 Aug 17.

College of Osteopathic Medicine of the Pacific, Western University of Health Sciences, Pomona, CA 91766, USA.

Dendritic cells are the principal antigen-presenting cells (APCs) in the host defense mechanism. An altered dendritic cell response increases the risk of susceptibility of infections, such as (), and the survival of the human immunodeficiency virus (HIV). The altered response of dendritic cells leads to decreased activity of T-helper-1 (Th1), Th2, Regulatory T cells (Tregs), and Th17 cells in tuberculosis (TB) infections due to a diminishment of cytokine release from these APCs, while HIV infection leads to DC maturation, allowing DCs to migrate to lymph nodes and the sub-mucosa where they then transfer HIV to CD4 T cells, although there is controversy around this topic.
