Inflammatory changes are observed in affected joints of osteoarthritis (OA) patients and are thought to be involved in the pathology that develops along OA progression. This narrative review provides an overview of the various cell types that are present in the joint during OA and which alarmins, cytokines, chemokines, growth factors, and other mediators they produce. Moreover, the involvement of more systemic processes like inflammaging and its associated cellular senescence in the context of OA are discussed.

UI	MeSH Term	Description	Entries
D007113	Immunity, Innate	The capacity of a normal organism to remain unaffected by microorganisms and their toxins. It results from the presence of naturally occurring ANTI-INFECTIVE AGENTS, constitutional factors such as BODY TEMPERATURE and immediate acting immune cells such as NATURAL KILLER CELLS.

D007249	Inflammation	A pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions. It is usually manifested by typical signs of pain, heat, redness, swelling, and loss of function.

D010003	Osteoarthritis	A progressive, degenerative joint disease, the most common form of arthritis, especially in older persons. The disease is thought to result not from the aging process but from biochemical changes and biomechanical stresses affecting articular cartilage. In the foreign literature it is often called osteoarthrosis deformans.

D000067531	Alarmins	A structurally diverse group of endogenous molecules that are multifunctional, having physiological functions inside the cell, but when released from dying cells or from cells under stress or certain immune cells, they function to activate INNATE IMMUNITY. Uncontrolled and excessive release of alarmins may contribute to INFLAMMATION; CARCINOGENESIS, and NEOPLASM METASTASIS. Alarmins are also critical for heart and nerve tissue homeostasis.

D016207	Cytokines	Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialized glands. They generally act locally in a paracrine or autocrine rather than endocrine manner.	Cytokine
D016922	Cellular Senescence	Process by which cells irreversibly stop dividing and enter a state of permanent growth arrest without undergoing CELL DEATH. Senescence can be induced by DNA DAMAGE or other cellular stresses, such as OXIDATIVE STRESS.
