This study focused on a condition called systemic sclerosis (SSc), an autoimmune disease that leads to thickening and scarring of the skin. Researchers found that certain proteins (CD13 and B1 receptor) were more active in the skin of patients with a severe form of SSc, contributing to excessive scar formation. By blocking the B1 receptor, they were able to reduce the fibrosis-related responses in lab tests and in mice, showing that this approach could be a new way to treat SSc. Who this helps: This helps patients with systemic sclerosis and their doctors by potentially offering a new treatment option.

This study looked at how a protein called GPNMB behaves in the skin cells of patients with diffuse cutaneous scleroderma (dcSSc), a condition that causes skin thickening. Researchers found that the levels of GPNMB were higher in skin cells from dcSSc patients compared to healthy individuals, with notable levels of its soluble form measured at 147.4 pg/ml versus 84.8 pg/ml. This protein appears to help reduce cell activity that leads to fibrosis, suggesting that boosting GPNMB could be a new way to treat scleroderma. Who this helps: This benefits patients with scleroderma.

This study looked at how blocking certain proteins called bromodomain extraterminal (BET) proteins can help reduce skin thickening in a condition known as scleroderma. The researchers found that using a drug called JQ1 to inhibit these proteins led to a significant reduction in fibrosis in lab animals and skin cells from scleroderma patients. Specifically, they observed changes in gene activity that affect cell growth and calcium levels, which are important for managing tissue fibrosis. Who this helps: This benefits patients with scleroderma by offering potential new treatment options.

Researchers discovered that a protein called CD13, which leaks into the bloodstream, causes inflammatory arthritis by activating a receptor called B1R found on joint cells. They confirmed this by showing that blocking B1R with drugs stopped the inflammation in multiple types of arthritis in mice and in human joint tissue samples. This matters because B1R could be a new drug target to treat rheumatoid arthritis and other inflammatory diseases by preventing CD13 from triggering joint inflammation.
