Erythroid progenitor cell

Erythroid progenitor cell (BFU-E, CFU-E): a progenitor committed to the erythroid lineage, arising from MEP in erythropoiesis; BFU-E needs SCF plus EPO, CFU-E depends on EPO alone, and CD71+ erythroid cells suppress immune responses.

Erythroid progenitor cell, mammalian

Mammalian erythroid progenitor cells, chiefly BFU-E and CFU-E, are EPO- and SCF-regulated, lineage-committed marrow and fetal-liver cells defined by colony-forming assays that generate red blood cells.

Erythrokeratodermia variabilis

Erythrokeratodermia variabilis (EKV, Mendes da Costa syndrome), now grouped as EKVP, is a rare connexin-gene inherited skin disorder with fixed hyperkeratotic plaques and transient migratory red patches, onset in infancy, autosomal dominant or recessive inheritance.

Erythrokeratodermia-cardiomyopathy syndrome

Erythrokeratodermia-cardiomyopathy (EKC) syndrome, ORPHA:476096, a rare autosomal dominant DSP-gene disorder combining generalized erythrokeratoderma, sparse hair, nail and enamel defects with progressive dilated cardiomyopathy.

Erythrolamprus

Erythrolamprus, coral snake mimics, is a Neotropical dipsadine snake genus of about 51 species in Central and South America, absorbing Liophis and Umbrivaga, with hidden diversity, toxic-frog prey resistance, and mild but real bites.

Erythromelalgia

Erythromelalgia, also called Mitchell's disease or erythermalgia, is a rare disorder of burning pain, redness, and heat in the extremities, relieved by cooling. Primary forms involve SCN9A/Nav1.7 mutations; secondary forms follow myeloproliferative and autoimmune disease; aspirin helps myeloproliferative cases.

Erythromycin

Erythromycin (Ilotycin) is a macrolide antibiotic from Saccharopolyspora erythraea that inhibits protein synthesis via 50S ribosome binding; used for respiratory, skin, and other bacterial infections, limited by GI effects, QT prolongation, CYP3A4 interactions, and resistance.

Erythromycin esterase

Erythromycin esterase (Ere) is a bacterial enzyme, first identified in E. coli in 1984, that inactivates macrolide antibiotics such as erythromycin by hydrolyzing their lactone ring, conferring high-level resistance.

Erythronium

Erythronium (fawnlily, trout lily, dog-tooth violet) is a genus of about 30 spring-flowering bulbous herbs in Liliaceae, native to the temperate Northern Hemisphere, with Eurasian, eastern North American, and western North American clades.

Erythronolide synthase

Erythronolide synthase (DEBS, 6-deoxyerythronolide B synthase) is the ~2 MDa modular type I polyketide synthase of Saccharopolyspora erythraea that assembles 6-dEB, the aglycone precursor of erythromycin A, from propionyl-CoA and six methylmalonyl-CoA units.

Erythroparvovirus primate1

Erythroparvovirus primate1 (Primate erythroparvovirus 1) is an ICTV parvovirus species whose exemplar virus is human parvovirus B19 (B19V), a 5,596-nt ssDNA virus causing fifth disease, aplastic crisis, and fetal hydrops.

Erythrophleum

Erythrophleum (ordeal tree genus) is a genus of 12 toxic legume tree species in Fabaceae, native to Africa, Madagascar, Asia, and Australia, containing the heart-poisoning alkaloid erythrophleine.

Erythrophore

Erythrophore: a neural crest-derived vertebrate pigment cell (chromatophore) with pteridine and carotenoid pigments in pterinosomes or erythrosomes, giving orange to red color; distinct from the yellow xanthophore and involved in fish and amphibian color change.

Erythropoiesis

Erythropoiesis is the production of red blood cells from hematopoietic stem cells via BFUe, CFUe, erythroblasts, and reticulocytes, regulated by kidney-derived erythropoietin and the HIF pathway, occurring in yolk sac, fetal liver, and bone marrow.

Erythropoietin

Erythropoietin (EPO), also called Hemopoietin, is a hormone produced mainly by the kidney that prompts red blood cell production; its recombinant forms treat anemia of chronic kidney disease.

Erythropoietin receptor

Erythropoietin receptor (EpoR, EPOR): homodimeric class I cytokine receptor for erythropoietin on erythroid progenitors; Jak2/STAT5 signaling; gene on 19p; central to the disputed non-hematopoietic and cancer expression controversy.

Erythrose 4-phosphate

Erythrose 4-phosphate (E4P) is a four-carbon sugar phosphate from the pentose phosphate pathway that, with PEP, initiates the seven-step shikimate pathway to chorismate and the aromatic amino acids; its low flux relative to PEP limits engineered aromatic compound production.

Erythrosine

Erythrosine, also known as FD&C Red No. 3, is a synthetic xanthene dye that colors foods and drugs red; the FDA revoked its food authorization in January 2025.

Erythroxylum

Erythroxylum (coca genus) is a pantropical genus of about 200-270 trees and shrubs in Erythroxylaceae, Malpighiales; includes Erythroxylum coca and E. novogranatense, source of cocaine, with intrapetiolar stipules and 10 fused stamens.

Erythrura

Erythrura (parrotfinches), genus of estrildid finches established by Swainson 1837; 10-12 species from southeast Asia to the Pacific; Gouldian Finch is its sister taxon.

Eryx (Sicily)

Eryx, modern Erice, is a hilltop town in western Sicily crowned by a sanctuary of Astarte, later Venus Erycina, a Carthaginian stronghold until 241 BC.

Erzg. aue

FC Erzgebirge Aue is a German football club from Aue in Saxony, founded in 1908, which won three East German championships as the Wismut works team.

Erzgebirge/Krušnohoří Mining Region

Erzgebirge/Krušnohoří Mining Region (Ore Mountains), a transboundary UNESCO World Heritage Site since 6 July 2019 with 22 component parts in Saxony and Czechia, preserving 800 years of silver, tin, cobalt, and uranium mining heritage.

Erzgebirgsstadion

Erzgebirgsstadion (eins-Erzgebirgsstadion since 2025), football stadium in Aue, Saxony, home of FC Erzgebirge Aue; built 1950 as Otto-Grotewohl-Stadion, rebuilt 2015-2017, capacity 15,500 covered places.
