Article Abstract

It has long been recognized that men and women have different degrees of susceptibility to chronic pain. Greater recognition of the sexual dimorphism in chronic pain has resulted in increasing numbers of both clinical and preclinical studies that have identified factors and mechanisms underlying sex differences in pain sensitization. Here, we review sexually dimorphic pain phenotypes in various research animal models and factors involved in the sex difference in pain phenotypes. We further discuss putative mechanisms for the sexual dimorphism in pain sensitization, which involves sex hormones, spinal cord microglia, and peripheral immune cells. Elucidating the sexually dimorphic mechanism of pain sensitization may provide important clinical implications and aid the development of sex-specific therapeutic strategies to treat chronic pain.

Background And Purpose: Socioeconomic determinants of health impact childhood development and adult health outcomes. One key aspect is the physical environment and neighborhood where children live and grow. Emerging evidence suggests that neighborhood deprivation, often measured by the Area Deprivation Index (ADI), may influence neurodevelopment, but longitudinal and multimodal neuroimaging analyses remain limited.

Response Characteristics of Barrel Cortical Neurons in Layers IV/V of Juvenile Rats with Autism-Like Traits after Tactile Stimulation.

The barrel cortex is a specialized region of the primary somatosensory cortex that processes tactile information from whiskers. This study investigates how tactile stimulation (TS) affects excitatory receptive fields and surrounds suppression in barrel cortex neurons of male and female autistic-like rats, using various whisker displacement protocols. The animals were categorized into control, Valproic acid pre-treated (Val), and Val-TS treatment groups.

Estrogen Receptor-α Loss Accelerates Cartilage Degradation through CLEC3B-Mediated Chondrocyte Hypertrophy and Inflammation.

Objective: Previous studies in our lab demonstrated that estrogen receptor-α (ERα) levels in cartilage decreased with osteoarthritis (OA). We also defined the essential role of ERα in maintaining the health of chondrocytes. However, most of the studies were conducted in vitro, and the physiological link between ERα loss and cartilage degradation has not been demonstrated using animal models.

In this longitudinal cohort study, we used nationally representative data from the U.S. National Health Interview Survey (n = 7,826 for chronic pain; n = 9,195 for high-impact chronic pain [HICP]) to examine the association of trouble sleeping and tiredness with 1-year incidence of chronic pain and HICP in U.
