Hif and hypoxia
Web27 de ago. de 2024 · Intratumoral hypoxia is a driving force for breast and liver cancer progression (2–4) that is mediated by hypoxia-inducible factors (HIFs), which are heterodimeric proteins consisting of an O 2-regulated HIF-1α, HIF-2α, or HIF-3α subunit and a constitutively expressed HIF-1β subunit . Web6 de out. de 2024 · Here we review the role of HIF in immunity, including its role in macrophages, dendritic cells, neutrophils, T cells, and B cells. Its role in immunity is as essential for cellular responses as it is in its original role in hypoxia, with HIF being implicated in multiple inflammatory diseases and in immunosuppression in tumors.
