Juxtaglomerular cells (JG cells), also known as juxtaglomerular granular cells are cells in the kidney that synthesize, store, and secrete the enzyme renin...

smooth muscle cells of the renal afferent arterioles, juxtaglomerular cells (JG cells), to release renin into the bloodstream. The JG cells can also release...

to the kidney will be sensed by baroreceptors in the Juxtaglomerular (JG) Cells of the afferent arteriole. If the decrease in blood pressure is systemic...

size from single cells to organisms weighing many tons Prokaryotes (small cylindrical cells, bacteria, on left) and a single-celled eukaryote, Paramecium...

Natural killer cells, also known as NK cells or large granular lymphocytes (LGL), are a type of cytotoxic lymphocyte critical to the innate immune system...

believed. B cells, unlike the other two classes of lymphocytes, T cells and natural killer cells, express B cell receptors (BCRs) on their cell membrane...

Cell division is the process by which a parent cell divides into two daughter cells. Cell division usually occurs as part of a larger cell cycle in which...

cell nucleus (from Latin nucleus or nuculeus 'kernel, seed'; pl.: nuclei) is a membrane-bound organelle found in eukaryotic cells. Eukaryotic cells usually...

one type of cell, but their initiation and continued growth are usually dependent on a single population of neoplastic cells. These cells are presumed...

flattened cells that overlie a base layer (stratum basale) composed of columnar cells arranged perpendicularly. The layers of cells develop from stem cells in...

high numbers of abnormal blood cells. These blood cells are not fully developed and are called blasts or leukemia cells. Symptoms may include bleeding...

Plasma cells, also called plasma B cells or effector B cells, are white blood cells that originate in the lymphoid organs as B cells and secrete large...

of cancer. Cell-based immunotherapies are effective for some cancers. Immune effector cells such as lymphocytes, macrophages, dendritic cells, natural killer...

denote a system of specialised cells that effectively clear colloidal vital stains (so called because they stain living cells) from the blood circulation...

Smith JG, et al. (December 2019). "ROS-mediated PI3K activation drives mitochondrial transfer from stromal cells to hematopoietic stem cells in response...

bacteria are now classified as prokaryotes. Unlike cells of animals and other eukaryotes, bacterial cells do not contain a nucleus and rarely harbour membrane-bound...

Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and...

Within the immune system, Follicular B cells (FO B cells) are a type of B cell that reside in primary and secondary lymphoid follicles (containing germinal...

response. In a T-cell dependent development pathway, naïve follicular B cells are activated by antigen-presenting follicular B helper T cells (TFH) during...

composition of its cell membrane to mimic the host cell membrane and avoid detection by immune system cells. M. pneumoniae cells possess a number of...
