Human synenkephalin [1–53] (hSYN), an analogue peptide of shrew saliva neurotoxins, was synthesized and its structural characteristics studied. Synthetic hSYN potently activated the T‐type voltage‐gated Ca channel hCav3.2 but did not paralyze mealworms. These findings offer new insight into neurological disorder treatment and evolutionary mechanisms of

The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

Inhibition of Food Intake by PACAP in the Hypothalamic Ventromedial Nuclei is Mediated by NMDA Receptors [PDF]
Central injections of pituitary adenylate cyclase-activating polypeptide (PACAP) into the ventromedial nuclei (VMN) of the hypothalamus produce hypophagia that is dependent upon the PAC1 receptor; however, the signaling downstream of this receptor in the

Neuropeptides and pharmacology [PDF]
The aim of the article is to briefly describe our work together with Dr. Viktor Mutt. He discovered and purified many new gastrointestinal bioactive neuropeptides that have important applications as therapeutic agents in diabetes, epilepsy, migraine and ...

The Semaphorin 3E (Sema3E)‐Plexin‐D1 pathway mediated by C/EBPα and C/EBPβ downstream of the luteinizing hormone (LH) surge plays important roles in the mouse preovulatory ovary. Timely activation and suppression of this pathway during the preovulatory stage are crucial for ovulation, corpus luteum formation, and proper angiogenesis.

Afferent Neuronal Control of Type-I Gonadotropin Releasing Hormone Neurons in the Human. [PDF]
Understanding the regulation of the human menstrual cycle represents an important ultimate challenge of reproductive neuroendocrine research. However, direct translation of information from laboratory animal experiments to the human is often complicated ...

Molecular Genetic Analysis of a Human Neuropeptide Y Receptor
Neuropeptide Y is a 36-amino-acid peptide amide with numerous biological activities. These functions are mediated through several pharmacologically distinct receptors. To date five receptor subtypes have been cloned.

Chronic social stress elevates oxytocin levels, leading to immunosuppression by enhancing regulatory T‐cell activity and promoting anti‐inflammatory macrophage polarization in the spleen. Blocking oxytocin signaling reverses these effects but worsens stress‐induced behavioral disorders and reduces survival rates. This highlights oxytocin's dual role in
