Hypoxia. 4. Hypoxia and ion channel function.
The ability to sense and respond to oxygen deprivation is required for survival; thus, understanding the mechanisms by which changes in oxygen are linked to cell viability and function is of great importance. Ion channels play a critical role in regulating cell function in a wide variety of biological processes, including neuronal transmission, control of ventilation, cardiac contractility, and...
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...
متن کاملHypoxia modulates human eosinophil function
BACKGROUND Eosinophils are involved in various inflammatory processes including allergic inflammation during which angiogenesis has been documented. Angiogenesis is most likely connected to the hypoxia which characterizes inflamed tissues. Eosinophils produce VEGF and are pro-angiogenic. However, to the best of our knowledge no study has been performed to verify the existence of a direct link b...
متن کاملEFFECTS OF HYPOXIC HYPOXIA AND CARBON MONOXIDE-INDUCED HYPOXIA ON THE CARDIOVASCULAR SYSTEM AND REGIONAL BLOOD FLOW OF THE ANESTHETIZED CAT
The purpose of this study was to investigate the potential responses of the cardiovascular system and regional blood flow to hypoxic hypoxia (BB) and to carbon monoxide (CO)-induced hypoxia (COH). Ten anesthetized cats were studied under two nonnoxic (control: CONT) and two hypoxic conditions. Four types of radioactive micro spheres were used to measure regional blood flow during CONT an...
متن کاملHypoxia. 5. Hypoxia and hematopoiesis.
Our understanding of organismal responses to hypoxia has stemmed from studies of erythropoietin regulation by hypoxia that led to the discovery of the master regulator of the hypoxic response, i.e., hypoxia-inducible factor (HIF). This is a transcription factor that is now known to induce the expression of a battery of genes in response to hypoxia. HIF-1 and HIF-2 regulate many genes that are i...
