A STAT1 gene provides instructions for making a protein that is involved in multiple immune system functions, including the body's defense against a fungus called Candida. When the immune system recognizes Candida, it generates cells called Th17 cells. These cells produce signaling molecules (cytokines) called the interleukin-17 (IL-17) family as part of an immune process called the IL-17 pathway. The IL-17 pathway creates inflammation, sending other cytokines and white blood cells that fight foreign invaders and promote tissue repair. In addition, the IL-17 pathway promotes the production of certain antimicrobial protein segments (peptides) that control growth of Candida on the surface of mucous membranes.

A STAT1 gene provides instructions for making a protein that is involved in multiple immune system functions, including the body's defense against a fungus called Candida. When the immune system recognizes Candida, it generates cells called Th17 cells. These cells produce signaling molecules (cytokines) called the interleukin-17 (IL-17) family as part of an immune process called the IL-17 pathway. The IL-17 pathway creates inflammation, sending other cytokines and white blood cells that fight foreign invaders and promote tissue repair. In addition, the IL-17 pathway promotes the production of certain antimicrobial protein segments (peptides) that control growth of Candida on the surface of mucous membranes.
The STAT1 protein helps keep the immune system in balance by controlling the IL-17 pathway. When the STAT1 protein is turned on (activated), it blocks (inhibits) this pathway.
In contrast to its inhibitory role in the IL-17 pathway, the STAT1 protein helps promote other immune processes called the interferon-alpha/beta (IFNA/B) and interferon-gamma (IFNG) signaling pathways. The IFNA/B pathway is important in defense against viruses, and the IFNG pathway helps fight a type of bacteria called mycobacteria, which includes the bacterium that causes tuberculosis.

Perda auditiva em pessoas idosas
Over half of people over the age of 60 have some degree of hearing loss. The exact cause of presbyacusis is not known. The inner ear (cochlea) contains nerve cells that convert sound into nervous impulses which are sent to the brain. It is thought that most people develop presbyacusis because these nerve cells don't seem to work as well and they.
