Viral infections are initiated by attachment of the virus to host cell surface receptors, including sialic acid-containing glycans. It is now possible to rapidly identify specific glycan receptors using glycan array screening, to define atomic-level structures of virus-glycan complexes and to alter the glycan-binding site to determine the function of glycan engagement in viral disease. This Review highlights general principles of virus-glycan interactions and provides specific examples of sialic acid binding by viruses with stalk-like attachment proteins, including influenza virus, reovirus, adenovirus and rotavirus. Understanding virus-glycan interactions is essential to combating viral infections and designing improved viral vectors for therapeutic applications.

Background: Chemokines and their receptors, which regulate lymphoid organ development and immune cell trafficking, are integral to the mechanisms underlying viral control, hepatic inflammation, and liver damage in chronic hepatitis C (CHC) infection. This study explores the potential relationship between serum chemokine levels/polymorphisms and hepatitis C infection in affected individuals, with a particular focus on their utility as biomarkers across different stages of fibrosis.

Methods And Results: Serum levels of the chemokines CXCL11, CXCL12, and CXCL16 were measured in patients with mild/moderate and advanced fibrosis due to CHC, as well as in healthy controls, using the ELISA method.

Infection with Neisseria gonorrhoeae, the causative agent of gonorrhoea, causes significant morbidity worldwide and can have long-term impacts on reproductive health. The greatest global burden of gonorrhoea occurs in low- and middle-income settings. Global public health significance is increasing due to rising antimicrobial resistance (AMR), which threatens future gonorrhoea management.
