The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [13] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...
Parietal epithelial cell (PEC) Podocyte; Angioblast → Endothelial cell; Mesangial cell. Intraglomerular; Extraglomerular; Juxtaglomerular cell; Macula densa cell; Stromal cell → Interstitial cell → Telocytes; Kidney proximal tubule brush border cell; Kidney distal tubule cell; Connecting tubule cells; α-intercalated cell; β-intercalated ...
The human genome, categorized by function of each gene product, given both as number of genes and as percentage of all genes. [7] Proteins may also be classified based on their cellular function. A widely used classification is PANTHER (protein analysis through evolutionary relationships) classification system. [7]
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
Phenethylamine is a potent agonist of the mouse, rat, and human trace amine-associated receptor 1 (TAAR1). [43] [2] β-PEA is also an odorant binding TAAR4 in mice thought to mediate predator avoidance. [44] Similarly to the case of amphetamine, phenethylamine shows enhanced locomotor stimulation, a psychostimulant-like effect, in TAAR1 ...

Aminopeptidases are a diverse group of enzymes that play crucial roles in various biological processes, including protein digestion, cell growth, and immune response.They are classified based on their substrate specificity (strength of binding) and catalytic mechanism (means of catalyzing their reaction) into two main categories: metalloaminopeptidases and cysteine aminopeptidases.
Cytochrome function is linked to the reversible redox change from ferrous (Fe(II)) to the ferric (Fe(III)) oxidation state of the iron found in the heme core. [2] In addition to the classification by the IUBMB into four cytochrome classes, several additional classifications such as cytochrome o [ 3 ] and cytochrome P450 can be found in ...
