Hypoxia-Inducible Hydrogels
Oxygen is vital for the existence of all multicellular organisms, acting as a signalling molecule regulating cellular activities. Specifically, hypoxia, which occurs when the partial pressure of oxygen falls below 5%, plays a pivotal role during development, regeneration and cancer. Here we report a novel hypoxia-inducible (HI) hydrogel composed of gelatin and ferulic acid that can form hydroge...
متن کاملSnapShot: Hypoxia-Inducible Factors
Molecular oxygen (O2) is a key substrate for mitochondrial ATP production and numerous intracellular biochemical reactions. The maintenance of O2 homeostasis is therefore essential for the survival of most species. During O2 deprivation, mammalian cells rely on multiple adaptations mediated by the hypoxia-inducible factors (HIFs), mTOR, autophagy, and the ER stress response. This SnapShot will ...
متن کاملHypoxia-inducible factor 1
Naïve T cells activated by antigen-presenting cells (APC) can be differentiated into at least four major types of T-helper (T(H)) cells: T(H)1, T(H)2, T(H)17 and inducible regulatory T cells (iTreg) based on their unique cytokine production profiles and characteristic functions.(1) T(H)1 produce interferon-γ (IFNγ) and are important for protective immune responses to intracellular viral, bacter...
متن کاملHypoxia and Hypoxia-Inducible Factors in Leukemias
Despite huge improvements in the treatment of leukemia, the percentage of patients suffering relapse still remains significant. Relapse most often results from a small number of leukemic stem cells (LSCs) within the bone marrow, which are able to self-renew, and therefore reestablish the full tumor. The marrow microenvironment contributes considerably in supporting the protection and developmen...
متن کاملHypoxia. Hypoxia, hypoxia inducible factor and myeloid cell function
With little in the way of effective therapeutic strategies to target the innate immune response, a better understanding of the critical pathways regulating neutrophil and macrophage responses in inflammation is key to the development of novel therapies. Hypoxia inducible factor (HIF) was originally identified as a central transcriptional regulator of cellular responses to oxygen deprivation. Ho...
