ה HTRA1 gene provides instructions for making a protein that is found in many of the body's organs and tissues. This protein is a type of enzyme called a serine protease, which has an active center that cuts (cleaves) other proteins into smaller pieces. The HTRA1 enzyme helps break down many other kinds of proteins in the space surrounding cells (the extracellular matrix).

ה HTRA1 gene provides instructions for making a protein that is found in many of the body's organs and tissues. This protein is a type of enzyme called a serine protease, which has an active center that cuts (cleaves) other proteins into smaller pieces. The HTRA1 enzyme helps break down many other kinds of proteins in the space surrounding cells (the extracellular matrix).
The HTRA1 enzyme also attaches (binds) to proteins in the transforming growth factor-beta (TGF-β) family and slows down (inhibits) their ability to send chemical signals. TGF-β proteins normally help control many critical cell functions, including the growth and division (proliferation) of cells, the process by which cells mature to carry out specific functions (differentiation), cell movement (motility), and the self-destruction of cells (apoptosis). TGF-β signaling also plays an important role in the formation of new blood vessels (angiogenesis).
Researchers have proposed several additional functions for the HTRA1 enzyme. It may play a role in the stabilization of microtubules, which are rigid, hollow fibers that make up the cell's structural framework (cytoskeleton). Additionally, the HTRA1 enzyme may be involved in depositing minerals, such as calcium and phosphorus, in developing bone (mineralization). Studies have also suggested that the HTRA1 enzyme acts as a tumour suppressor, a protein that helps prevent the development of cancerous tumours by keeping cells from growing and dividing in an uncontrolled way.

Other treatments Studies have shown that the use of a medication called tocilizumab alongside the steroids improves the chances of stopping or reducing the steroids without relapse. In the UK, the National Institute for Health and Care Excellence (NICE) guidance is currently that this should only be used in people who have already had a relapse or.

אבנים בכליות
אבנים בכליות are hard stones that can cause severe pain in your side along with blood in your urine, and nausea and vomiting. You are more likely to develop kidney stones if you eat a Western diet, don't drink enough fluids or are overweight. Once you have had one episode they are likely to recur but there are several kidney stone treatment.

Telogen effluvium (hair loss) is a condition where more than normal amounts of hair fall out. There is a general 'thinning' of the hair. Many other medications have been linked to telogen effluvium, but some of the most common are beta-blockers; retinoids, including excess vitamin A (often used for skin problems); anticoagulants (often called.
