The discovery of numerous potent and broad neutralizing antibodies (bNAbs) against Human Immunodeficiency Virus type 1 (HIV-1) envelope glycoprotein has invigorated the potential of using them as an effective preventative and therapeutic agent. The majority of the anti-HIV-1 antibodies, currently under clinical investigation, are formulated singly for intra-venous (IV) infusion. However, due to the high degree of genetic variability in the case of HIV-1, a single broad neutralizing antibody will likely not be sufficient to protect against the broad range of viral isolates.

Article Synopsis
  • The study aims to enhance the accuracy of measuring intact proteins, antibodies, and peptides while minimizing interaction with silanols from HPLC columns.
  • By adding Hydroxypropyl ß Cyclodextrin (HPCD) at various concentrations in the mobile phase, researchers test different SEC-HPLC columns to evaluate performance improvements for biologics of varying molecular weights.
  • Results show that HPCD increases peak resolution, height, and overall quantification of biologics without causing protein aggregation, leading to more efficient separation and accurate measurements.

Effective anti-tumour immunity in humans has been associated with the presence of T cells directed at cancer neoantigens, a class of HLA-bound peptides that arise from tumour-specific mutations. They are highly immunogenic because they are not present in normal tissues and hence bypass central thymic tolerance. Although neoantigens were long-envisioned as optimal targets for an anti-tumour immune response, their systematic discovery and evaluation only became feasible with the recent availability of massively parallel sequencing for detection of all coding mutations within tumours, and of machine learning approaches to reliably predict those mutated peptides with high-affinity binding of autologous human leukocyte antigen (HLA) molecules.
