IL1 and megakaryocytes in obesity (Homo sapiens)
From WikiPathways
Description
Schematic of the effects of interleukin (IL)1β/IL1R1 on megakaryocyte and platelet function. A high fat diet will cause megakaryocytes to produce platelets with an increase in both inflammatory and thrombotic genes.
IL1β in circulation as a result of increased body weight will bind IL1R1 on megakaryocytes. This interaction leads to the activation of the nuclear factor (NF)κB, PI3K/Akt, and mitogen activated protein kinase (MAPK) (ERK and p38) pathways. As a result, there is an increase in megakarycoyte maturation, including increased adhesion, increases in ploidy, and increases in mRNA production of inflammatory and thrombotic genes. IL1β can also bind IL1R1 on platelets and either enhance aggregation induced by agonists or promote adhesion and heterotypic aggregate formation.
