Researchers have made significant strides in understanding and combating both viral and fungal threats, according to multiple reports. Discoveries range from a broadly protective antibody against gammaherpesviruses to a fungal solution for bark beetle infestations.
Cryoelectron microscopy revealed the molecular basis for broad gB binding and cross-genus virus neutralization by an antibody called Fab5, according to a Nature News report. This antibody offers effective protection against authentic virus challenges in immune-competent mice, non-human primates, and humanized mice with murine, rhesus, and human gammaherpesvirus. The discovery demonstrates Fab5 as a cross-genus antibody broadly reactive against gammaherpesvirus infection and pathogenesis progression. This finding not only demonstrates Fab5 as cross-genus antibody broadly reactive against gammaherpesvirus infection and pathogenesis progression, but offers insights into potential common mechanisms for herpesvirus infection and facilitates the development of broad-spectrum vaccines against the gammaherpesvirus. Gammaherpesvirus is a subfamily of herpesvirus, distinct phylogenetically from alpha- and betaherpesvirus and featured by its oncogenic subtypes, including Epstein-Barr virus and Kaposis sarcoma-associated herpesvirus. It broadly infects humans and other vertebrate animals and causes various diseases and malignancies. Currently, there are no specific antiviral agents available for each type or the whole family.
In a separate development, scientists at the Max Planck Institute discovered that specific strains of the Beauveria bassiana fungus can effectively combat bark beetle infestations, which are exacerbated by climate change. Multiple news sources reported that these fungal strains overcome the beetles' defenses, offering a potential alternative to traditional insecticides. The discovery offers a promising development in pest control.
In other news, various reports also highlighted concerns about potential political interference in appointments at the National Institutes of Health (NIH), the declining sales of Asda, and the unearthing of a massive archaeological collection from HS2 railway construction. The archaeological find includes a secret warehouse containing 450,000 objects.
