Despite its toxicity, a great deal of attention has been paid to the anorexic effect of capsaicin in the treatment of obesity-related neurotransmitters/neuromodulators. To determine if capsaicin has any effects on the orexigenic or anorexigenic peptides, the neuropeptide Y (NPY)- and cholecystokinin (CCK)-immunoreactivities were demonstrated in the rat hypothalamus by immunohistochemistry after capsaicin administration. There was a significantly lower concentration of NPY immunopositive cells…

Immunohistochemical changes in orexigenic and anorexigenic neuropeptides in the rat hypothalamus after capsaicin administration.

The results indicate that capsaicin reduces food intake, not body weight, transiently, and decreases AgRP and orexin immunoreactivities, whereas it increases alpha-MSH and ACTH immunoreActivities in rat hypothalamic nuclei.

Circulating GLP-1 and CCK-8 reduce food intake by capsaicin-insensitive, nonvagal mechanisms.

The results indicate that vagal or capsaicin-sensitive neurons are not necessary for reduction of food intake by circulating (endocrine) GLP-1, or cholecystokinin, and that vaginal participation in satiation by these peptides may be limited to paracrine effects exerted near the sites of their secretion.

The endocannabinoid-CB receptor system: a new player in the brain-gut-adipose field

TheECBR system is a major mediator between the brain and the alimentary system, and possibly, the adipose tissue, and the role of the ECBR system in adult regulation of food processing is a remnant of its critical role for the initiation of feeding in the newborn.

Comparison of the antiobesity effects of the protopanaxadiol‐ and protopanaxatriol‐type saponins of red ginseng

The results suggest that the antiobesity activity of PD and PT type saponins may result from inhibiting energy gain, normalizing hypothalamic neuropeptides and serum biochemicals related to the control of obesity.

Biološki učinci kapsaicina

Capsaicinoids (capsaicin, dihydrocapsaic in, nordihydrocapsicin, homodihydroapsaicIN, homocapsaicIn, norcapsaic in and nornorcapsaicins) are alkaloid alkaloids that have anti-inflammatory properties.



Capsaicin-sensitive fibers are required for the anorexic action of systemic but not central bombesin.

This research suggests that peripheral BN communicates with the brain via a neuronal system(s) whose afferent arm is constituted of capsaicin-sensitive C and/or Adelta-fibers, whereas the efferent arm of this satiety- and-or anorexia-mediating circuitry is Capsaicin resistant.

Alterations in brain cholecystokinin receptors after fasting

Fasting in mice significantly increases CCK binding due to an increased number of CCK receptors in the olfactory bulb and hypothalamus, but not in other brain regions, and this finding supports the concept that CCK regulates satiety through interaction with this brain region.

Cholecystokinin octapeptide-like immunoreactivity: histochemical localization in rat brain.

Cholecystokinin octapeptide-like (CCK-OP-like) immunoreactivity was localized in the rat brain by using the indirect immunofluorescence method. Specificity in immunohistochemical studies was

Neuronal localization of cholecystokinin mRNA in the rat brain by using in situ hybridization histochemistry

The results demonstrate a widespread distribution of neurons containing CCK mRNA throughout the rat brain and clearly identify the existence of CCK‐synthesizing neurons in regions such as the paraventricular and supraoptic nuclei of the hypothalamus, where the presence ofCCK cell bodies was previously uncertain.
