Skeletal muscle has recently been identified as an endocrine organ. It has, therefore, been suggested that cytokines and other peptides that are produced, expressed, and released by muscle fibers and exert paracrine, autocrine, or endocrine effects should be classified as "myokines." Recent research demonstrates that skeletal muscles can produce and express cytokines belonging to distinctly different families. However, the first identified and most studied myokine is the gp130 receptor cytokine…

Muscles, exercise and obesity: skeletal muscle as a secretory organ
TLDR
The finding that the muscle secretome consists of several hundred secreted peptides provides a conceptual basis and a whole new paradigm for understanding how muscles communicate with other organs, such as adipose tissue, liver, pancreas, bones and brain.
IL-6 myokine signaling in skeletal muscle : a double-edged sword ?
TLDR
Several members of the interleukin-6 (IL-6) family, particularly IL-6 and leukemia inhibitory factor (LIF), have been recognized as myokines, that is, cytokines produced by the working skeletal muscle during exercise, and their possible biological implications.
Muscular interleukin-6 and its role as an energy sensor.

TLDR
The discovery of contracting muscle as a cytokine-producing organ opens for a whole new paradigm: if the endocrine function of the muscle is not stimulated through contractions, it will cause malfunction of several organs and tissues of the body.
Anti-Inflammatory Effect of Muscle-Derived Interleukin-6 and Its Involvement in Lipid Metabolism
TLDR
Why IL-6 has different functions, the signaling mode of hyper-IL-6 via soluble IL- 6 receptor (sIL- 6R), and the involvement of soluble glycoprotein 130 in the suppressive effect ofhyper-il-6 are discussed.
Muscle as an Endocrine Organ
Skeletal muscle secretion of IL-6 is muscle type specific: Ex vivo evidence.
Muscle endocrinology and its relation with nutrition
TLDR
Adequate nutrition during ages plays a fundamental role in the health and function of the skeletal muscle and it can represents, alone or in combination with physical exercise, a possible preventive measure against sarcopenia.
Muscle-to-organ cross talk mediated by myokines
TLDR
It is found that CXCL-1 overexpression increases muscular fatty acid oxidation with concomitant attenuation of diet-induced fat accumulation in the adipose tissue, adding to the concept of myokines playing an important role in mediating the whole-body adaptive effects of exercise through the regulation of skeletal muscle metabolism.
Cytokine expression and secretion by skeletal muscle cells: regulatory mechanisms and exercise effects.
TLDR
The capacity of skeletal muscle cells to produce cytokines is summarized, other potential cellular sources of circulating cytokines during exercise are analyzed, and the soluble factors and intracellular signaling pathways that regulate cytokine synthesis are discussed.
Distinguished Lecture : Muscle as an endocrine organ : IL-6 and other myokines
TLDR
The finding that muscles produce and release myokines creates a paradigm shift and opens new scientific, technological, and scholarly horizons and contributes to the understanding of why regular exercise protects against a wide range of chronic diseases.

Signaling pathways for IL-6 within skeletal muscle.
TLDR
It is clear that IL-6 production is activated by intracellular calcium levels, mitogen-activated protein kinases, reduced glycogen availability and other cytokines such as IL-1 beta, and relatively less is known regarding the upstream factors that induce the transcription of IL- 6.
The role of IL-6 in exercise-induced immune changes and metabolism.
TLDR
The possible beneficial biological role of high plasma levels of IL-6 during exercise is discussed, because carbohydrate ingestion during exercise has been demonstrated to blunt theIL-6 and hormonal response, it might also blunt other beneficial adaptations.
Beneficial health effects of exercise--the role of IL-6 as a myokine.
Muscle-derived interleukin-6: lipolytic, anti-inflammatory and immune regulatory effects
TLDR
The data support the hypothesis that the role of IL-6 released from contracting muscle during exercise is to act in a hormone-like manner to mobilize extracellular substrates and/or augment substrate delivery during exercise.

TLDR
It appears that intramuscular IL‐6 is stimulated by complex signaling cascades initiated by both calcium (Ca2+) ‐dependent and ‐independent stimuli, and it also seems likely that skeletal muscle produces IL‐ 6 to aid in maintaining metabolic homeostasis during periods of altered metabolic demand such as muscular exercise or insulin stimulation.
Role of myokines in exercise and metabolism.
TLDR
The present review focuses on muscle-derived cytokines, their regulation by exercise, and their possible roles in metabolism and skeletal muscle function and it discusses which cytokines should be classified as true myokines.
The metabolic role of IL-6 produced during exercise: is IL-6 an exercise factor?
TLDR
It is suggested that muscle-derived IL-6 fulfils the criteria of an exercise factor and that such classes of cytokines could be termed ‘myokines’.
THIS ARTICLE HAS BEEN RETRACTED Exercise induces interleukin‐8 expression in human skeletal muscle
TLDR
A marked IL‐8 protein expression was demonstrated within the cytoplasm of muscle fibres in biopsy samples obtained in the recovery phase following 3 h of bicycle exercise, and the peak occurred 3–6 h postexercise, suggesting that muscle‐derivedIL‐8 may play a local role, e.g. in angiogenesis.
Interleukin-6 in acute exercise and training: what is the biological relevance?
TLDR
Extended exercise involving a significant muscle mass in the contractile activity is necessary in order to produce a marked systemic IL-6 response, and exercise training may reduce basalIL-6 production as well as the magnitude of the acute exercise IL- 6 response by counteracting several potential stimuli of IL-8.
Interleukins and exercise
TLDR
The paper by Steensberg et al. (2000) in this issue of The Journal of Physiology is the first study to describe an increase in the net release of interleukin-6 (IL-6) from exercising skeletal muscle in humans and the authors suggest a hormone-like glucoregulatory role for this cytokine.
