Lymphocytic choriomeningitis virus injures the developing brain: effects and mechanisms.

Lymphocytic choriomeningitis virus (LCMV) is a prevalent pathogen, whose natural host and reservoir is the wild mouse. Humans can be infected when they contact the secretions of mice. Most infections of postnatal humans result in mild illness.

Measles Virus and the Central Nervous System: An Update.

Sequelae Renee Buchanan, Daniel J. Bonthius Seminars in Pediatric Neurology Volume 19, Issue 3, September 2012, Pages 107-114 Worldwide, measles remains one of the most deadly vaccine-preventable diseases. In the United States, enrollment in the public schools requires that each child receives 2 doses of measles-containing vaccine before entry, essentially eliminating this once endemic disease.

Lgr5-expressing secretory cells form a Wnt inhibitory niche in cartilage critical for chondrocyte identity.

Osteoarthritis is a degenerative joint disease that causes pain, degradation, and dysfunction. Excessive canonical Wnt signaling in osteoarthritis contributes to chondrocyte phenotypic instability and loss of cartilage homeostasis; however, the regulatory niche is unknown. Using the temporomandibular joint as a model in multiple species, we identify Lgr5-expressing secretory cells as forming a Wnt inhibitory niche that instruct Wnt-inactive chondroprogenitors to form the nascent synovial joint and regulate chondrocyte lineage and identity.

Purkinje cell-specific deletion of CREB worsens alcohol-induced cerebellar neuronal losses and motor deficits.

Introduction: Exposure to alcohol during pregnancy can kill developing fetal neurons and lead to fetal alcohol spectrum disorder (FASD) in the offspring. However, not all fetuses are equally vulnerable to alcohol toxicity. These differences in vulnerability among individuals are likely due, at least in part, to genetic differences.

Structure-function relationships of TMJ lateral capsule-ligament complex.

The human temporomandibular joint (TMJ) lateral capsule ligament (LCL) complex is debated as a fibrous capsule with distinct ligaments or ligamentous thickening, necessitating further evaluation of the complex and its role in TMJ anatomy and mechanics. This study explores the ultrastructural arrangement, biomechanical tensile properties, and biochemical composition of the human LCL complex including region-specific differences to explore the presence of a distinct temporomandibular ligament and sex-specific differences to inform evaluations of potential etiological mechanisms. LCL complex ultrastructural arrangement, biomechanical properties, and biochemical composition were determined using cadaveric samples.
