GABAB receptor‐mediated modulation of sensory neuron excitability: Roles of CaV2.2, G‐protein‐coupled inwardly rectifying potassium (GIRK) channels, and hyperpolarisation‐activated cyclic nucleotide‐gated (HCN) channels in human and mouse nociception

open access: yesExperimental Physiology, EarlyView.
Abstract Chronic visceral pain is a key symptom of irritable bowel syndrome. Modulation of voltage‐gated calcium and potassium channels by G protein‐coupled receptors plays a key role in dampening nociceptive transmission. Both baclofen and the analgesic peptide α‐conotoxin Vc1.1 activate GABAB receptors (GABABR), resulting in inhibition of CaV2.2 and ...

Affective CT‐touch attenuates cortical responses and subjective attention during temporal summation of second pain

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The study investigated the modulatory effects of affective touch on temporal summation of second pain (TSSP) in 32 romantic couples (N = 64). The design included a dyadic session (partner's CT‐optimal stroking vs. static touch) and an individual session (robotic CT‐touch vs. vibration control).

Bidirectional Roles of TRPV1 in a Latent Sensitization Model of Myofascial Low Back Pain

open access: yesEuropean Journal of Pain, Volume 30, Issue 4, April 2026.
ABSTRACT Introduction Chronic primary low back pain (cpLBP) is a global health concern with poorly understood pathomechanisms, potentially involving spinal sensitization. The capsaicin receptor TRPV1 plays a crucial role in sensitization across pain models.

Global Burden of Sickle Cell Disease: Adequacy of Pain Control as Evidenced by Frequency of Oral Pain Medication Use, Health Outcomes, and Emotional Well‐Being Across Diverse Populations

open access: yeseJHaem, Volume 7, Issue 2, April 2026.
ABSTRACT Introduction Sickle cell disease (SCD) is a chronic genetic disorder causing severe pain, anemia, and systemic complications that negatively affect patients’ physical and mental well‐being. The aim of this global cross‐sectional study was to evaluate the relationship between oral pain medication (OPM) use frequency and health outcomes ...

Does acetaminophen activate endogenous pain inhibition in chronic fatigue syndrome/fibromyalgia and rheumatoid arthritis? : a double-blind randomized controlled cross-over trial [PDF]

open access: yes, 2013
Background: Although enhanced temporal summation (TS) and conditioned pain modulation (CPM), as characteristic for central sensitization, has been proved to be impaired in different chronic pain populations, the exact nature is still unknown. Objectives:

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 ...

Axon Initial Segment: Structure, Biological Functions, Diseases, and Therapeutic Targets

open access: yesMedComm, Volume 7, Issue 4, April 2026.
The axon initial segment (AIS) is a specialized axonal domain critical for maintaining neuronal polarity, action potential initiation, and network stability. This review summarizes the necessary elements for maintaining AIS structure and plasticity, discussing crucial biological functions of AIS in neuronal signaling and the neural circuit homeostasis,

The mutual effect of progesterone and vitamin D in an animal model of peripheral nerve injury

open access: yesResearch in Pharmaceutical Sciences
Background and purpose: Experimental and clinical studies have shown the potential role of progesterone in relieving neural injury. In addition, emerging data on vitamin D, a steroid hormone, have shown its neuroprotective properties.
