Broadly neutralizing humanized SARS-CoV-2 antibody binds to a conserved epitope on Spike and provides antiviral protection through inhalation-based delivery in non-human primates.

The COVID-19 pandemic represents a global challenge that has impacted and is expected to continue to impact the lives and health of people across the world for the foreseeable future. The rollout of vaccines has provided highly anticipated relief, but effective therapeutics are required to further reduce the risk and severity of infections. Monoclonal antibodies have been shown to be effective as therapeutics for SARS-CoV-2, but as new variants of concern (VoC) continue to emerge, their utility and use have waned due to limited or no efficacy against these variants.

Expanding the Malaria Antibody Toolkit: Development and Characterisation of RH5, CyRPA, and CSP Recombinant Human Monoclonal Antibodies.

Malaria, an infection caused by apicomplexan parasites of the genus , continues to exact a significant toll on public health with over 200 million cases world-wide, and annual deaths in excess of 600,000. Considerable progress has been made to reduce malaria burden in endemic countries in the last two decades. However, parasite and mosquito resistance to frontline chemotherapies and insecticides, respectively, highlights the continuing need for the development of safe and effective vaccines.

ACE2 Peptide Fragment Interaction with Different S1 Protein Sites.

Unlabelled: We study the effect of the peptide QAKTFLDKFNHEAEDLFYQ on the kinetics of the SARS-CoV-2 spike protein S1 binding to angiotensin-converting enzyme 2 (ACE2), with the aim to characterize the interaction mechanism of the SARS-CoV2 virus with its host cell. This peptide corresponds to the sequence 24-42 of the ACE2 α1 domain, which marks the binding site for the S1 protein. The kinetics of S1-ACE2 complex formation was measured in the presence of various concentrations of the peptide using bio-layer interferometry.

EPHA2 Polymorphisms in Estonian Patients with Age-Related Cataract.

Background: Ephrin receptors (Ephs) are tyrosine kinases that together with their ligands, ephrins, are considered important in cell-cell communication, especially during embryogenesis but also for epithelium homeostasis. Studies have demonstrated the involvement of mutations or common variants of the gene encoding Eph receptor A2 (EPHA2), in congenital cataract and in age-related cataract. This study investigated a number of disease-associated single nucleotide polymorphisms (SNPs) in EPHA2 in patients with age-related cataract.
