Adeno‐associated virus serotype 2 capsid variants for improved liver‐directed gene therapy

Hepatology, EarlyView., 2022
Abstract Background and Aims Current liver‐directed gene therapies look for adeno‐associated virus (AAV) vectors with improved efficacy. With this background, capsid engineering is explored. Whereas shuffled capsid library screenings have resulted in potent liver targeting variants with one first vector in human clinical trials, modifying natural ...

A bacteriophage-acquired O-antigen polymerase (Wzyβ) from P. aeruginosa serotype O16 performs a varied mechanism compared to its cognate Wzyα.

Frontiers in Microbiology, 2016
Pseudomonas aeruginosa is a Gram-negative bacterium that produces highly varied lipopolysaccharide (LPS) structures. The O antigen (O-Ag) in the LPS is synthesized through the Wzx/Wzy-dependent pathway where lipid-linked O-Ag repeats are polymerized by ...

New Pneumococcal Serotype 15D

Journal of Clinical Microbiology, 2021
The pneumococcal serogroup 15 comprises four capsular polysaccharide serotypes (15A, 15B, 15C, 15F) that collectively account for an impactful disease burden ([1][1], [2][2]). These four serotypes are defined by Quellung reaction typing, employing specific serologic factor sera to visualize ...
