Down-regulation of GAS6 by M1 macrophages resulted in impaired efferocytosis for synovial apoptotic cells, causing synovial hyperplasia and obesity-associated OA development.

The ovarian immune system ages while coping with the two main challenges of the aging ovary before menopause, the inflammatory stimulations due to repeated cycles and the increasing need for clearance of accumulating atretic follicles.

Lack of aryl hydrocarbon receptor ligands in the diet of mice increases the inflammatory state in their epidermis, making cutaneous allergic reactions more severe and airway allergy more pronounced after skin sensitization.

Gut macrophages produce complement component C1q, which modulates neurogenic activity of gut peristalsis and is thus a key regulator of gastrointestinal motility.

CX3CR1-positive dendritic cells are altered in patients with non-infectious uveitis.

Oligodendroglia express major histocompatibility complex (MHC) pathways in response to inflammation and MHC reporter mice allow for the investigation of MHC molecule expressing cells in vivo.

High cerebrospinal fluid tryptophan levels consistently predict increased mortality in HIV-infected and -uninfected patients in Vietnam and Indonesia.

Selective involvement of Arp2/3 complex subunit isoforms ARPC5 or ARPC5L governs the distinct actin polymerization events in the nucleus or cytoplasm of CD4 T cells that are triggerd by T cell activation or DNA replication stress.

The small macrophage-secreted protein RELMα is a sex-specific protein that protects against diet-induced obesity through regulating the macrophage–eosinophil innate immune axis in the adipose tissue.

Human macrophages infected with Mycobacterium tuberculosis present peptides derived from substrates of type VII secretion systems on MHC class I via a pathway dependent on the ESX-1 secretion system and independent of antigen processing by the proteasome and cathepsins.
