Anti-immune complex antibodies are elicited during repeated immunization with HIV Env immunogens

Vaccination strategies against HIV-1 aim to elicit broadly neutralizing antibodies (bnAbs) using prime-boost regimens with HIV envelope (Env) immunogens. Epitope mapping has shown that early antibody responses are directed to easily accessible nonneutraliz ...

Local structural flexibility drives oligomorphism in computationally designed protein assemblies

Aleksandar Antanasijevic

Many naturally occurring protein assemblies have dynamic structures that allow them to perform specialized functions. For example, clathrin coats adopt a wide variety of architectures to adapt to vesicular cargos of various sizes. Although computational me ...

Enterovirus A71 priorities, challenges, and future opportunities in humoral immunity and vaccine development

Aleksandar Antanasijevic

Enterovirus A71 (EV-A71) is a significant public health concern, particularly in the Asia-Pacific region, where it commonly causes hand, foot, and mouth disease outbreaks. There are no clinically available antivirals, and use of inactivated vaccine is rest ...

Inhibition of Influenza Entry by Organosilicon Compounds

Aleksandar Antanasijevic

Hemagglutinin (HA) plays a critical role in the entry of influenza and thus HA is a target for the development of entry inhibitors as antivirals. One of the first small molecule inhibitors of influenza entry to be described was tert‐butylhydroquinone (TBHQ ...

Virus adaptation to heparan sulfate comes with capsid stability tradeoff

Matteo Dal Peraro, Aleksandar Antanasijevic, Valeria Cagno

Because of high mutation rates, viruses constantly adapt to new environments. When propagated in cell lines, certain viruses acquire positively charged amino acids on their surface proteins, enabling them to utilize negatively charged heparan sulfate (HS) ...

Missense variants in CMS22 patients reveal that PREPL has both enzymatic and nonenzymatic functions

Matteo Dal Peraro, Maria Josefina Marcaida Lopez, Aleksandar Antanasijevic, Anastasia Theodoropoulou, Edoardo Cavani

Congenital myasthenic syndrome-22 (CMS22, OMIM 616224) is a rare genetic disorder caused by deleterious genetic variation in the prolyl endopeptidase-like (PREPL) gene. Previous reports have described patients with deletions and nonsense variants in PREPL, ...

Influence of Amino Acid Substitutions in Capsid Proteins of Coxsackievirus B5 on Free Chlorine and Thermal Inactivation

Tamar Kohn, Aleksandar Antanasijevic, Shotaro Torii, Kiruthika Kumar

The sensitivity of enteroviruses to disinfectants varies among genetically similar variants and coincides with amino acid changes in capsid proteins, although the effect of individual substitutions remains unknown. Here, we employed reverse genetics to inv ...

Glycan heterogeneity as a cause of the persistent fraction in HIV-1 neutralization

Philippe Colin, Aleksandar Antanasijevic

Neutralizing antibodies (NAbs) to multiple epitopes on the HIV-1-envelope glycoprotein (Env) have been isolated from infected persons. The potency of NAbs is measured more often than the size of the persistent fraction of infectivity at maximum neutralizat ...
