Fatty acid metabolism in the regulation of T cell function

The specific regulation of cellular metabolic processes is of major importance for directing immune cell differentiation and function. We review recent evidence indicating that changes in basic cellular lipid metabolism have critical effects on T cell proliferation and cell fate decisions. While ind...

C5a and Neutrophils as Early Mediators in Inflammatory Arthritis

Researchers from the Massachusetts General Hospital (MGH) have studied the initial steps in an animal model of inflammatory arthritis and found that complement C5a is critical to neutrophils migration into joints. The findings of these early events in the inflammatory cascade were published in Scien...

Pathologically expanded peripheral T helper cell subset drives B cells in rheumatoid arthritis

CD4+ T cells are central mediators of autoimmune pathology; however, defining their key effector functions in specific autoimmune diseases remains challenging. Pathogenic CD4+ T cells within affected tissues may be identified by expression of markers of recent activation. Here we use mass cytometry…
