Despite several decades of investigation, the manner in which foot-and-mouth disease virus (FMDV) interacts with the innate and adaptive immune compartments is not completely understood. The importance of elucidating this relationship is emphasized by the inability of current FMDV vaccines to provide long-term protection and the recent outbreaks of FMDV in formerly disease-free countries. Dendritic cells (DCs) are professional antigen-presenting cells that have evolved to monitor the environment and provide a link between the innate and adaptive immune systems. Comprehending the cross-talk between DC and FMDV will provide valuable information towards understanding the host response to the virus and will aid in the design of effective tools and vaccines to block virus spread.

Sheeppox and Goatpox are highly contagious transboundary viral diseases of sheep and goats caused by Capripoxvirus, respectively. This study describes the development of indirect ELISA and its serodiagnostic potential as an alternative to the gold standard serum neutralization test (SNT). The homologue of vaccinia virus, ORF 117 (A27L) gene of the Romanian Fenner (RF) strain of Sheeppox virus (SPPV) was used for producing the full-length recombinant A27L (rA27L) protein (∼22 kDa) in a prokaryotic expression system.

Exosomes, small extracellular vesicles secreted by various cells, play crucial roles in the pathogenesis and treatment of oral diseases. Recent studies have highlighted their involvement in orthodontics, periodontitis, oral squamous cell carcinoma (OSCC), and hand, foot, and mouth disease (HFMD). Exosomes have a positive effect on the inflammatory environment of the oral cavity, remodeling and regeneration of oral tissues, and offer promising therapeutic options for bone and periodontal tissue restoration.

Enterovirus 71 (EV-71) is a major pathogenic factor that causes hand, foot, and mouth disease in young children and infants. Given the limited treatments for EV-71 infection, discovering new host factors and understanding the mechanisms involved will aid in combating this viral infection. Neutral sphingomyelinase-2 (nSMase-2, encoded by SMPD3) is a crucial cellular cofactor in viral infection.

Cell culture underpins virus isolation and virus neutralisation tests, which are both gold-standard diagnostic methods for foot-and-mouth disease (FMD). Cell culture is also crucial for the propagation of inactivated foot-and-mouth disease virus (FMDV) vaccines. Both primary cells and cell lines are utilised in FMDV isolation and propagation.

The accessibility of genetic data will facilitate a more comprehensive delineation of FMDV phylogeny on a global scale. In this study, we investigated the FMDV strains circulating in Russia during the 2013-2014 period in geographically distant regions utilizing whole genome sequencing followed by maximum-likelihood phylogenetic reconstruction of whole genome and VP1 gene sequences.
