What are adipokines and cytokines?
Adipokines are a family of hormones and cytokines with both pro- and anti-inflammatory effects that are secreted by adipose tissue. Family members include the aforementioned TNF-α and IL-6 (pro-inflammatory), leptin, and adiponectin, among others.
Is leptin an Adipokine?
Leptin is a pleiotropic adipokine with diverse effects on cell types throughout the body. Its role in neuroendocrine signaling, homeostasis, and metabolism has been well studied.
What is adipokines function?
Adipokines are important modulators of appetite and satiety, energy expenditure and activity, fat distribution, adipocyte function, glucose and lipid metabolism, insulin sensitivity, chronic inflam- mation, and other processes. Over recent years, many novel adipokines have been discovered.
Are adipokines anti-inflammatory?
The adipokines possess pro- and anti-inflammatory properties and play a critical role in integrating systemic metabolism with immune function.
Is adipokine anti-inflammatory?
Adiponectin acts by binding to its receptors, and it possesses anti-inflammatory, anti-atherogenic, and insulin-sensitizing properties.
Are adipokines pro inflammatory?
What adipokine causes insulin resistance?
Inflammatory responses in adipose tissues become self-generating that eventually leads to increased local and systemic levels of various pro-inflammatory cytokines including tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), IL-1β, and CC-chemokine ligand 2 (CCL2) that are causative for insulin resistance.
What is leptin made of?
Leptin (from the Greek word leptos, meaning “thin”) is derived from the lep gene, located on chromosome 7, which transcribes a 167 amino acid peptide with a molecular weight of 16kD.
Are adipokines hormones?
Abstract. Adipose-tissue (AT) is an endocrine organ that dynamically secretes multiple hormones, the adipokines, which regulate key physiological processes.
