From Gut to Systemic Circulation: Molecular Strategies of Botulinum Neurotoxin Complexes [PDF]

Toxins
Botulinum neurotoxins (BoNTs), among the most potent biological toxins, rely on co-produced nontoxic proteins to survive harsh gastrointestinal conditions and achieve efficient systemic dissemination after oral exposure.

Laboratory approaches in desensitization for ABO-incompatible transplantation [PDF]

Clinical Transplantation and Research
ABO-incompatible transplantation, once considered contraindicated due to the risk of hyperacute rejection, has become a viable option owing to advances in immunosuppression and desensitization methods. Accurate measurement and effective reduction of anti-

Human Immunity and Susceptibility to Influenza A(H3) Viruses of Avian, Equine, and Swine Origin

Emerging Infectious Diseases, 2023
Influenza A viruses (IAVs) of subtype H3 that infect humans are antigenically divergent from those of birds, horses, and swine. Human immunity against these viruses might be limited, implying potential pandemic risk. To determine human risk, we selected

Porphyromonas gingivalis-Helicobacter pylori co-incubation enhances Porphyromonas gingivalis virulence and increases migration of infected human oral keratinocytes

Journal of Oral Microbiology, 2022
Background Porphyromonas gingivalis is part of the subgingival biofilm and a keystone species in the development of periodontitis. Interactions between P.gingivalis and other bacteria in biofilms have been shown to affect bacterial virulence ...

Hemagglutinin Structure and Activities [PDF]

Cold Spring Harbor Perspectives in Medicine, 2020
Hemagglutinins (HAs) are the receptor-binding and membrane fusion glycoproteins of influenza viruses. They recognize sialic acid-containing, cell-surface glycoconjugates as receptors but have limited affinity for them, and, as a consequence, virus attachment to cells requires their interaction with several virus HAs. Receptor-bound virus is transferred

Influenza Virus Infection Induces a Narrow Antibody Response in Children but a Broad Recall Response in Adults

mBio, 2020
In contrast to influenza virus vaccination, natural infection induces long-lived and relatively broad immune responses. However, many aspects of the antibody response to natural infection are not well understood.
