[Prostasin (PRSS8) as a new pathological factor].
Prostasin (PRSS8) regulates glucose homeostasis through Toll-like receptor 4 (TLR4) signaling, offering new insights into diabetes development linked to obesity and inflammation.
Area of Science:
- Biochemistry
- Physiology
- Immunology
Context:
- Serine proteases are crucial for vital biological functions.
- Prostasin (PRSS8), a serine protease, is widespread in human tissues.
- The exact physiological function of PRSS8 remains largely unknown.
Purpose:
- To review the current understanding of prostasin (PRSS8).
- To highlight PRSS8's newly identified role in glucose homeostasis regulation.
- To explore PRSS8's involvement in diseases linked to metabolic dysfunction.
Summary:
- Recent research reveals prostasin (PRSS8) regulates glucose homeostasis via Toll-like receptor 4 (TLR4)-mediated signaling in the liver.
- This finding provides novel insights into diabetes development, particularly in contexts of obesity-induced inflammation and metabolic endotoxemia.
- The review consolidates current knowledge on PRSS8's pathological significance in human diseases.
Impact:
- Establishes PRSS8 as a potential factor in metabolic diseases like diabetes.
- Suggests TLR4 signaling as a key pathway influenced by PRSS8 in metabolic regulation.
- Opens avenues for investigating PRSS8 as a therapeutic target for metabolic disorders.

In this pathway, the target proteins are first tagged with small proteins called ubiquitin. A series of enzymes carry out the ubiquitination of the target proteins - E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...
