Multiplex immunohistochemistry - Anti-Aquaporin 2 antibody [EPR21080] (AB199975)

Multiplex immunohistochemistry analysis of formalin/PFA-fixed paraffin-embedded human kidney tissue staining CD34 with ab317588 at a 1/2000 dilution, ab199975 anti-Aquaporin 2 used at 1/4000 dilution and ab212197 anti-Renin used at a 1/4000 dilution.

Panel A : merged staining of anti-CD34 (green; Opal™520), anti-Aquaporin 2 (magenta; Opal™690) and anti-Renin (gray; Opal™570) on human kidney.

Panel B : anti-CD34 staining endothelium in human kidney.

Panel C : anti-Aquaporin 2 staining collecting tubules in human kidney.

Panel D : anti-Renin staining juxtaglomerular cells in human kidney.

Nuclear DNA was labeled with DAPI (shown in blue).

The section was incubated in three rounds of staining : in the order of ab317588, ab199975 and ab212197 for 30 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system.

The immunostaining was performed on a Leica Biosystems BOND® RX instrument with an Opal™ 4-color kit. Image acquisition was performed with Leica SP8 confocal microscope.

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins.

Aquaporin 2 often referred to as AQP2 or aquaporin-2 channels is a water channel protein facilitating water transport across cell membranes. This protein belongs to the larger family of aquaporins which includes variants such as aquaporine often referred to interchangeably. Aquaporin 2 is a glycosylated integral membrane protein with an estimated mass of about 29 kDa. It expresses mainly in the kidney specifically in the collecting duct cells where it plays a pivotal role in water reabsorption.
Biological function summary

Aquaporin 2 serves a critical function in maintaining body water balance homeostasis. AQP2 responds to vasopressin a hormone that triggers its translocation to the apical membrane of collecting duct cells enabling water permeability. It is not part of a broader protein complex but operates independently within the cell membrane. This activity regulates urine concentration contributing to the maintenance of body fluids under variable hydration conditions.

Pathways

Aquaporin 2 contributes prominently to the vasopressin-regulated water reabsorption pathway and relates to the renal water reabsorption pathway. These pathways are important for interpreting how water homeostasis is managed by the body. Proteins such as the vasopressin receptor (also known as AVPR2) interact directly with AQP2 enabling its regulation and function. The interaction with cAMP signaling pathways facilitates the relocation of aquaporin 2 to its active site on the cell membrane ensuring efficient water reabsorption.

Mutations or dysregulation in aquaporin 2 can cause conditions like nephrogenic diabetes insipidus characterized by an inability to concentrate urine leading to excessive urination and thirst. Another disorder associated with AQP2 is syndrome of inappropriate antidiuretic hormone secretion (SIADH). These conditions highlight the importance of aquaporin 2 in fluid homeostasis and they connect it to regulatory proteins such as vasopressin itself emphasizing the interconnected nature of cellular proteins in disease mechanisms.

Target data

Forms a water-specific channel that provides the plasma membranes of renal collecting duct with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient (PubMed : 15509592, PubMed : 7510718, PubMed : 7524315, PubMed : 8140421, PubMed : 8584435). Plays an essential role in renal water homeostasis (PubMed : 15509592, PubMed : 7524315, PubMed : 8140421). Could also be permeable to glycerol (PubMed : 8584435).
