juxtaglomerular cell

At the same time, the juxtaglomerular cells sense the decrease in blood pressure and release renin.

These juxtaglomerular cells play a major role in the renin-angiotensin system, which helps regulate blood volume and pressure.

Similar to cardiac tissue, juxtaglomerular cells harbor β1 adrenergic receptors.

One cause is a juxtaglomerular cell tumor.

Increase renin secretion from juxtaglomerular cells of the kidney.

In appropriately stained slides, juxtaglomerular cells are distinguished by their granulated cytoplasm.

When blood volume is low, juxtaglomerular cells in the kidneys secrete renin directly into circulation.

Angiotensin is stimulated by the juxtaglomerular cells when renal blood pressure drops below 90 mmHg.

The juxtaglomerular cells secrete renin in response to:

Renin release from juxtaglomerular cells.

It contains three components: the macula densa, juxtaglomerular cells, and extraglomerular mesangial cells.

If less Na+ is sensed by the macula densa, renin release by juxtaglomerular cells is increased.

Juxtaglomerular cell tumor (reninoma)

In turn, the decreased flow and pressure to the kidney will be sensed by baroreceptors in the Juxtaglomerular Cells of the afferent arteriole.

Furthermore, a low volume also stimulates sympathetic nerves, which stimulate renin release from the juxtaglomerular cells of the afferent arteriole in the kidneys.

(2) it increases renin release from the juxtaglomerular cells of the afferent and efferent arterioles, which are the major storage sites for renin.

The juxtaglomerular cells (JG cells, or granular cells) are cells in the kidney that synthesize, store, and secrete the enzyme renin.

Polkissen cells aka juxtaglomerular cells are located between the afferent and efferent arterioles at the vascular pole of the glomerulus, adjacent to the macula densa.

Second, macula densa cells release prostaglandins, which triggers granular juxtaglomerular cells lining the afferent arterioles to release renin into the bloodstream.

The three cellular components of the apparatus are the macula densa of the distal convoluted tubule, smooth muscle cells of the afferent arteriole and juxtaglomerular cells.

Prorenin concentration increased proportionally less than active renin concentration with enalapril than with hydrochlorthiazide, which suggests that juxtaglomerular cell stimulation with enalapril was ineffective.

They are also known as juxtaglomerular cells (juxtaglomerular cells are not granular cells but are granulated as they release renin).

Renin is secreted by renal juxtaglomerular cells and catalyses the conversion of angiotensinogen into angiotensin I which is the rate-limiting step in the production of angiotensin II.

The differential diagnosis of kidney cancer in a young patient with hypertension includes juxtaglomerular cell tumor (reninoma), Wilms' tumor, and renal cell carcinoma, all of which may produce renin.

In alternative fashion, a decrease in the filtrate NaCl concentration and/or decreased filtrate flow rate will stimulate the macula densa to signal the juxtaglomerular cells to release renin.
