Fluorescence multiplex immunohistochemical analysis of human adrenal gland (formalin-fixed paraffin-embedded section). Panel A shows merged staining of anti-PCSK2 stained on adrenal medulla (ab274418; gray; Opal™690) at 1 : 2000 (0.263 μg/ml) [Panel B], anti-CYP11A1 stained on adrenal cortex (ab272494; green; Opal™520) at 1 : 10000 (0.053 μg/ml) [Panel C], and anti-Neuropeptide Y stained on chromaffin cells (ab221145; red; Opal™570) at 1 : 2000 (0.279 μg/ml) [Panel D] on human adrenal gland. DAPI was used as a nuclear counter stain. Followed by Opal Polymer HRP Ms + Rb secondary antibody. 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. The section was incubated in three rounds of staining : in the order of ab274418, ab272494, and ab221145 for 30 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins was used.  This data was developed using ab221145, the same antibody clone in a different buffer formulation.

Supplementary information

Neuropeptide Y (NPY) a 36 amino acid peptide functions mechanically as a neurotransmitter in the central and peripheral nervous systems. Alternate names include porcine peptide YY. The molecular weight of Neuropeptide Y is approximately 4 kDa. It expresses primarily in regions of the brain such as the hypothalamus and sympathetic nervous system as well as in other tissues including the heart adrenal glands and white adipose tissue.
Biological function summary

Neuropeptide Y plays an important role in regulating various physiological processes. It is not typically part of a complex but acts directly on specific receptors mainly Y1 Y2 Y4 and Y5. Neuropeptide Y affects food intake behavior stress response circadian rhythm and cardiovascular regulation. It does so by modulating the release of other neurotransmitters or hormones having a significant impact on energy balance and homeostasis.

Pathways

Neuropeptide Y plays a pivotal role in neurobiological signaling pathways especially those involving stress and energy homeostasis. In the hypothalamus NPY influences energy balance by interacting with the melanocortin pathway an important modulator of appetite and energy expenditure. It also interacts with proteins such as pro-opiomelanocortin (POMC) in these signaling pathways highlighting its integration into complex physiological processes that maintain homeostasis.

Neuropeptide Y shows a significant connection to metabolic disorders and stress-related conditions. Dysregulation of NPY signaling has been implicated in obesity given its role in promoting food intake and energy storage. Additionally altered Neuropeptide Y activity links to anxiety and depression diseases involving stress-response dysregulation. Proteins like leptin which interacts with NPY in pathways governing hunger and energy allocation provide another layer of regulation affecting these conditions.
