Feline Calicivirus Infection: Current Understanding and Implications for Control Strategies

Feline calicivirus (FCV) is a highly contagious pathogen widely circulating in cat populations. FCV has been shown to be able to evade the host immune response through different mechanisms. As a result, following the acute phase of infection, some cats remain persistently infected or experience reinfection cycles with variants of the same strain or with distinct field FCVs. These animals may become asymptomatic carriers, assuming a critical role in virus transmission and posing a significant ...

Evidence of Chronic Tusk Trauma and Compensatory Scoliosis in Mammuthus meridionalis from Madonna della Strada (Scoppito, L’Aquila, Italy)

A remarkably well-preserved skeleton of a male Mammuthus meridionalis, approximately 60 years old, from the Early Pleistocene that is housed at the Castle of L’Aquila (Italy) exhibits a fractured left tusk with severe bone erosion of the alveolus and premaxillary bone, as well as marked spinal deformities. The cranial region underwent ultrasonographic, radiological, and histological examinations, while morphological and biomechanical analyses were conducted on the vertebral column. Microscopi...

Type-1 Cannabinoid Receptor Promiscuous Coupling: Computational Insights into Receptor-G Protein Interaction Dynamics

Cannabinoid receptor (CB1), a G protein coupled receptor (GPCR), is a known pharmacological target in several diseases and modulates key physiological processes through Gi protein-mediated signaling. However, recent evidence suggests that CB1 can also activate other G proteins, including the stimulatory Gs protein, a phenomenon with unclear structural determinants. Here, we use a computational approach to elucidate the structural basis of the CB1-Gs interaction. Protein–protein docking a...
