Summary
This study highlights the emerging roles of Interleukin-31 (IL-31) and Interleukin-33 (IL-33) in osteoporosis. The IL-33/IL-31 axis offers potential new therapeutic targets for treating bone loss.
Area of Science:
- Immunology
- Bone Biology
- Osteoporosis Pathogenesis
Background:
- The immunoskeletal interface reveals cytokines regulating bone remodeling and osteoporosis.
- Th1 and Th17 inflammatory cytokines are known contributors to osteoporosis.
- Emerging research implicates novel Th2 cytokines, IL-31 and IL-33, in osteoporosis.
Purpose of the Study:
- To investigate the emerging roles of Interleukin-31 (IL-31) and Interleukin-33 (IL-33) in osteoporosis.
- To elucidate the implications of the IL-33/IL-31 axis in bone remodeling and osteoporosis pathogenesis.
Main Methods:
- Clinical and experimental observations were utilized.
- The study focused on the interplay between IL-33, IL-31, Th2 cells, and osteoclastogenesis.
Main Results:
- IL-33 induces IL-31 secretion from Th2 cells and inhibits RANKL-dependent osteoclastogenesis, counteracting bone loss.
- IL-31 promotes Th1/Th17-mediated osteoclastogenic inflammation and limits protective Th2 processes, thus exacerbating osteoporosis.
- The IL-33/IL-31 axis appears to play a significant role in osteoporosis.
Conclusions:
- Understanding the roles of IL-31 and IL-33 in osteoporosis is crucial.
- Targeting IL-31, IL-33, and their receptor complexes may offer novel therapeutic strategies for osteoporosis with potentially fewer side effects.

01:31Osteoclasts in Bone Remodeling
3.7K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

01:17Hormones and Bone Tissue
3.6K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:40Bone Remodeling
40.1K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:29Bone Disorders
5.0K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:25Role of Vitamins in Maintaining Bone Health
4.8K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

01:16TGF - β Signaling Pathway
10.3K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...
