Receptorium histamini H4, abbreviatura HRH4 est receptorium histamini et familiae receptoriorum proteino G copulatorum.

Stimulatio HRH4 chemotaxem mastocytorum atque muitationem formae granulocytorum eosinophilorum contrahit[1]. In testium cellulis Leydigiensibus steroidogenesem receptoriorum H4 ope inhibere videtur[2].

Agonista est Clozapinum, antagonista Pimozidum.

Polymorphismi geni receptorii cancrum contrahere potest.

Historia[recensere | fontem recensere]

In anno 2000 essentia receptorii histamini H4 descripta est[3][4]. Exaequatum cum geno receptorii histamini H3 40% aminoacidorum illis HRH4 aequalia sunt.

Natura receptorii histamini H4[recensere | fontem recensere]

Natura genetica[recensere | fontem recensere]

Genum receptorii histamini H4, HRH4 nominatum, chromosomate 18 locatum est.

Structura receptorii[recensere | fontem recensere]

Receptorium ex 390 aminoacidis constitutum est.

HRH4 et cancer[recensere | fontem recensere]

Mutatio geni receptorii histamini H4 nonnumquam formas cancri instigare videtur, ut cancrum pulmonis.

Cancer pulmonis[recensere | fontem recensere]

Cuique polymorphismorum geneticorum periculum deformationis carcinomatosae pulmonum inhabitet. Transitio carcinomatosa in cancros pulmonis non cellularum parvarum in parte polymorphismo geni receptorii H4 sociatus sit[5].
