5-HT6R Viral Vector-Mediated Indirect Pathway Activation in the Dorsolateral Striatum: A Discussion on Basal Ganglia Habitual and Goal-Directed Circuits [PDF]

open access: yes, 2018
Altering maladaptive behavioral tendencies is relevant for clinical interventions, making research on underlying mechanisms of habit essential. Mechanisms of habit are explored here with differential activation of the indirect pathway in the basal ...

Physical activity moderates the relationship between hot flashes and arterial wave reflection in perimenopausal females

open access: yesPhysiological Reports, Volume 14, Issue 10, May 2026.
Abstract Subclinical CVD risk factors are associated with hot flashes (HF). Habitual physical activity (PA) reduces CVD risk in part due to effects on blood vessel characteristics. The objective was to evaluate associations between arterial wave reflection (WR), HFs, and PA in perimenopausal people and determine whether PA moderates the relationship ...

Stress rapidly suppresses in vivo LH pulses and increases activation of RFRP-3 neurons in male mice [PDF]

open access: yes, 2018
Restraint stress is a psychosocial stressor that suppresses reproductive status, including LH pulsatile secretion, but the neuroendocrine mechanisms underlying this inhibition remains unclear.

Unraveling Chronic Pain: From Mechanisms and Risks to Diagnosis and Treatment

open access: yesMedComm, Volume 7, Issue 4, April 2026.
Chronic pain arises through distinct molecular pathways categorized into nociceptive, neuropathic, and nociplastic types. Nociceptive pain begins with TRP channel activation in peripheral nociceptors, signaling via Aδ‐ and C‐fibers through the spinal dorsal horn and spinothalamic tracts to the brain, regulated by descending inhibition and involving ...

Opioid precursor protein isoform is targeted to the cell nuclei in the human brain [PDF]

open access: yes, 2017
Background: Neuropeptide precursors are traditionally viewed as proteins giving rise to small neuropeptide molecules. Prodynorphin (PDYN) is the precursor protein to dynorphins, endogenous ligands for the kappa-opioid receptor.

Understanding cell‐penetrating peptide mechanisms using computational electrophysiology simulations

open access: yesProtein Science, Volume 35, Issue 4, April 2026.
Abstract Cell‐penetrating peptides (CPPs) can enter cells without inducing cytotoxicity and can be coupled with cargo molecules to be used to deliver drugs, DNA, or nanoparticles into cells. The peptide‐membrane interactions driving the internalization mechanism are not completely understood. In this study, we introduce Computational Electrophysiology (

High-frequency stimulation-induced peptide release synchronizes arcuate kisspeptin neurons and excites GnRH neurons

open access: yeseLife, 2016
Kisspeptin (Kiss1) and neurokinin B (NKB) neurocircuits are essential for pubertal development and fertility. Kisspeptin neurons in the hypothalamic arcuate nucleus (Kiss1ARH) co-express Kiss1, NKB, dynorphin and glutamate and are postulated to provide ...

Placenta ingestion by rats enhances d- and k-opioid antinociception, but suppresses m-opioid antinociception [PDF]

open access: yes, 2004
Ingestion of placenta or amniotic fluid produces a dramatic enhancement of centrally mediated opioid antinociception in the rat. The present experiments investigated the role of each opioid receptor type (m, d, k) in the antinociception-modulating ...

AAKD: A standardized and comprehensive acupuncture anesthesia knowledge platform for enhanced recovery after surgery and mechanism

open access: yesVIEW, Volume 7, Issue 2, April 2026.
Acupuncture anesthesia (AA) is an application of acupuncture innovation in surgical operations, combined with anesthetic techniques, and is a model of integrated Chinese and Western medicine. We proposed the Acupuncture Anesthesia Knowledge Database (AAKD), in which all data have been meticulously curated by field experts and assessed by a multi ...
