Neurotrophic Receptor Tyrosine Kinase or NTRK is a superfamily of receptor tyrosine kinases[1] these are protein-encoding genes that may be linked to myalgic encephalomyelitis/chronic fatigue syndrome.[2]

NTRK1[edit | edit source]

Neurotrophic Tyrosine Kinase Receptor 1 is one of the NTKR family of protein-encoding genes.[3]

ME/CFS[edit | edit source]

Almenar-Pérez et al (2020) found that NTRK appeared to be affected in patients with severe ME/CFS, which could relate to "symptoms such as cognitive disability and sensorial dysfunctions (altered pain sensitivity)44".[2] In this small study of patients with severe ME, NTRK1 levels were found to be significantly higher in the severely ill patients compared to healthy controls.[2]

ME/CFS - An acronym that combines myalgic encephalomyelitis with chronic fatigue syndrome. Sometimes they are combined because people have trouble distinguishing one from the other. Sometimes they are combined because people see them as synonyms of each other.

extracellular vesicle - An extracellular vesicle (sometimes abbreviated EV) is a piece of a cell that has broken off and formed a separate membrane-bound vesicle. A membrane-bound vesicle is like a bubble, or like a mini-cell, in that it has a membrane surrounding some liquid. An extracellular vesicle may also contain some parts of the cell from which the extracellular vesicle arose. There are currently two types of extracellular vesicles: "exosomes" and "microvesicles". An "exosome" is an extracellular vesicle that began inside the cell as an intracellular vesicle known as an "endosome". A "microvesicle" is an extracellular vesicle that begins at the cell surface, and pinches off the cell's own membrane to form a separate vesicle. (Learn more: journals.physiology.org)

myalgic encephalomyelitis (ME) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.

chronic fatigue syndrome (CFS) - A controversial term, invented by the U.S. Centers for Disease Control, that generally refers to a collection of symptoms as “fatigue”. There have been multiple attempts to come up with a set of diagnostic criteria to define this term, but few of those diagnostic criteria are currently in use. Previous attempts to define this term include the Fukuda criteria and the Oxford criteria. Some view the term as a useful diagnostic category for people with long-term fatigue of unexplained origin. Others view the term as a derogatory term borne out of animus towards patients. Some view the term as a synonym of myalgic encephalomyelitis, while others view myalgic encephalomyelitis as a distinct disease.
