Monitoring the VDPV2 outbreak in Egypt during 2020–2021 highlights the crucial role of environmental surveillance and boosting immunization in combating Poliovirus

BMC Infectious Diseases
Background Poliovirus is a highly infectious enterovirus (EV) that primarily affects children and can lead to lifelong paralysis or even death. Vaccine-derived polioviruses (VDPVs) are a great threat since they are derived from the attenuated virus in ...

Human Circulating Antibody-Producing B Cell as a Predictive Measure of Mucosal Immunity to Poliovirus.

PLoS ONE, 2016
BackgroundThe "gold standard" for assessing mucosal immunity after vaccination with poliovirus vaccines consists in measuring virus excretion in stool after challenge with oral poliovirus vaccine (OPV).

Three-dimensional structure of poliovirus receptor bound to poliovirus [PDF]

Proceedings of the National Academy of Sciences, 2000
Poliovirus initiates infection by binding to its cellular receptor (Pvr). We have studied this interaction by using cryoelectron microscopy to determine the structure, at 21-Å resolution, of poliovirus complexed with a soluble form of its receptor (sPvr). This density map aided construction of a homology-based model of sPvr and, in conjunction with the

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Importation and Circulation of Vaccine-Derived Poliovirus Serotype 2, Senegal, 2020–2021

Emerging Infectious Diseases, 2022
Environmental surveillance for poliovirus is increasingly used in poliovirus eradication efforts as a supplement to acute flaccid paralysis (AFP) surveillance. Environmental surveillance was officially established in 2017 in Senegal, where no poliovirus

A Personalised Vaccination Program Based on Immune Reconstitution in Paediatric Cancer Survivors

Acta Paediatrica, EarlyView.
ABSTRACT Aims Paediatric cancer survivors often experience treatment‐induced immunosuppression, requiring post‐treatment revaccination. However, immune recovery timelines vary, and current revaccination guidelines, largely based on data of varied quality derived from studies on acute‐lymphoblastic‐leukaemia (ALL), may not be applicable across all ...

Will containment of wild poliovirus in laboratories and inactivated poliovirus vaccine production sites be effective for global certification?

Bulletin of the World Health Organization
The absolute laboratory containment of any virus cannot be guaranteed, but a wealth of experience indicates that effective containment of wild poliovirus materials for global certification is technically and operationally feasible.

Therapeutic potential of natural products in cancer immunotherapy: Advances and challenges

British Journal of Pharmacology, EarlyView.
This review systematically outlines the mechanisms underlying tumour immunotherapy resistance and elucidates the role of natural products in enhancing therapeutic efficacy as immunomodulatory adjuvants. Abstract Immunotherapy has emerged as a clinically pivotal approach in cancer treatment, but its application remains limited to a small subset of ...
