Insect I‐Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates

Advanced Science, Volume 13, Issue 1, 5 January 2026.
Upon rice viral infection, the insect vector activates the Toll–MyD88–Dorsal signaling cascade, inducing i‐type lysozyme (Lyz‐I1) expression. Lyz‐I1 functions as an antiviral protease through its conserved catalytic dyad Glu/Asp (E/D), mediating cleavage of viral proteins at specific Lys (K) residues.

RNAi Regulator C3PO Promotes Arbovirus Infection in Insect Vectors

Advanced Science, Volume 13, Issue 4, 19 January 2026.
RNA interference (RNAi) is vital for eukaryotes to defend against virus infection. The C3PO complex takes part in RNAi but its role in regulating viral infection remains unclear. This work finds that insect C3PO facilitates arbovirus replication by degrading precursors of miRNAs, especially miR‐971‐3p.

Characterization of a new Autographa californica multiple nucleopolyhedrovirus (AcMNPV) polyhedra mutant [PDF]

, 2009
In the very late phase of baculovirus infection, virions are occluded in a crystalline matrix called polyhedra, which is mainly composed of polyhedrin. This protein is highly conserved among baculoviruses and changes in its amino acid sequence may lead ...

Update of the list of QPS‐recommended biological agents intentionally added to food or feeds as notified to EFSA

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The qualified presumption of safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of relevant knowledge and safety concerns of microorganisms intentionally added to the food and feed chain.

A Role for the Anti-Viral Host Defense Mechanism in the Phylogenetic Divergence in Baculovirus Evolution. [PDF]

PLoS ONE, 2016
Although phylogenic analysis often suggests co-evolutionary relationships between viruses and host organisms, few examples have been reported at the microevolutionary level. Here, we show a possible example in which a species-specific anti-viral response
