KININS AND NEUROPEPTIDES | Tachykinins

G.F. Joos, K. De Swert, in Encyclopedia of Respiratory Medicine, 2006

Immunomodulation

Tachykinins are known to have a wide variety of modulatory effects on inflammatory and immune cells. Substance P degranulates mast cells, leading to the release of histamine and 5-hydroxytryptamine (5-HT, serotonin), and the production of tumor necrosis factor alpha (TNF-α). Tachykinins cause adherence and chemotaxis of human neutrophils. Substance P induces chemotaxis of human eosinophils. Several in vitro and in vivo studies have shown that substance P is able to modulate the chemotaxis, proliferation, and activation of lymphocytes. Tachykinins also have a number of stimulatory effects on monocytes and macrophages: substance P has been shown to evoke superoxide anion production, enhance phagocytosis, and cause production of interleukin-1 and interleukin-12 by macrophages. Tachykinins are also able to activate mesenchymal cells in the airways.

Entrez Gene Summary for TAC4 Gene

  • This gene is a member of the tachykinin family of neurotransmitter-encoding genes. Tachykinin proteins are cleaved into small, secreted peptides that activate members of a family of receptor proteins. The products of this gene preferentially activate tachykinin receptor 1, and are thought to regulate peripheral endocrine and paracrine functions including blood pressure, the immune system, and endocrine gland secretion. The products of this gene lack a dibasic cleavage site found in other tachykinin proteins. Consequently, the nature of the cleavage products generated in vivo remains to be determined. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Long covid: Plasmalipidiepätasapainoa

https://link.springer.com/chapter/10.1007%2F978-3-030-50621-6_7 

Kerään tähän arikkeleita ,joita pitää harkiten lukea.

Aivojen plasmalipeideissä on  pieni osa fosfatidyylilipidejä, lipositoleja, ja niillä on oma tärkeä modulinsa varsinkin  harmaissa  hermosoluissa. Niillä on erittäin funktionaalinen modulinsa (, josta tässä fytiiniblogissa olen käsitellyt eri molekyylejä vuosien varrella. Covidin jälkeen on havaittu fosfolipidikirjossa  epätasapainoa ja  korostuneeksi näyttää jäävän  tästä  lipositolimodulipuolesta lyso-muotoa, lysofosfolipidiä lysofosfatidyyli-inositolia.  Asian taustalla piilee  sars-2 viruksen raju  soluaineenvaihdunnan manipulointi, joka jättää siten jälkeensä tälle  inositolia sisältävälle järjestelmälle mahdollisuuden paisua.   Tämä heijastuu kyllä  psyykiseen toimitnaan lähinnä mielialaan monivivahteisesti, josmistä  pitää saada  ajan mitaan  tarpeeksi käsitystä . Muuten ei  pääse jyvälle siitä, millä tavalla voi johtaa metaboliaa korjaantumiskynnyksen paremmalle puolelle. Itsestään korjaantuvuus kudoksissa ihmisellä on hyvä, muta  on jokin kynnys joka  pitää ylittää, että päästään sellaisen normaliteetin puolelle.  Kyse ei ole vain aivojen inositolimodulista, vaan myös kohdista josa tätä  modulia käytetään. Yksi on  sokeriaineenvaihdunta.  Ilmeisesti vaaraa on keuhkofibroosista ja  non-alkoholisesta  maksanrasvoittumisestakin jos tämä ei oikene.  Viruksen yksi tapa moduloida  energia-aineita näyttää olleen ATP, CTP, TTP ja  TTP  peräisten energioiden  purkaminen, fosfaattien irrottaminen ja samalla GTP-peräisen energian suosiminen. En tiedä jos tässä olen  asiasta jyvällä. Tällöin on paljon  tarjolla esim AMP ja CMP- muotoa, joita   oinositoliaineenvaihdunta käyttää.   aivojen puolella  lysofosfatidylinositoli muodostaa  protektiivisuutta  erään artikkelin mukaanJos  ATP ja CTP  ovat purkaantuneita ,  fosfatidyyli-inositoli ei pysty nousemaan energiarikakisiin muotoihinsa.

Covidin jälkeen fosfolipidien profiiliin tulee epätasapainoa. Lysofosfatidyyli-inositolia ja fosfatidyyli-inositolia tavallista enemmän, muita vähemmän

 Aiemmin ei ole huomiotani kiinnittänyt  lysofosfatidyyli-inositoli, joten otan siitä  tietoa esiin nyt.
