Role of Viral Envelope Proteins in Determining Susceptibility of Viruses to IFITM Proteins.

Interferon-induced transmembrane proteins (IFITMs) are a family of proteins which inhibit infections of various enveloped viruses. While their general mechanism of inhibition seems to be non-specific, involving the tightening of membrane structures to prevent fusion between the viral envelope and cell membrane, numerous studies have underscored the importance of viral envelope proteins in determining the susceptibility of viruses to IFITMs. Mutations in envelope proteins may lead to viral escape from direct interaction with IFITM proteins or result in indirect resistance by modifying the viral entry pathway, allowing the virus to modulate its exposure to IFITMs.

Dose-dependent effects of antibiotic intake on Bombus Terrestris (Linnaeus, 1758) dietary intake, survival and parasite infection prevalence.

Diseases may contribute to the widespread declines seen in many bee species. The gut bacteria of bees may serve as one defence against disease, by preventing pathogen colonisation. However, exposure to antibiotics on forage or in the hive may disrupt bee gut bacteria and remove this protective effect.
