AI Article Synopsis

  • The study aimed to develop human single-chain Fv (scFv) antibodies that specifically target the pathogenic bacteria Burkholderia mallei and Burkholderia pseudomallei for diagnostic and therapeutic uses.
  • Two panning procedures were utilized on a human scFv antibody library, resulting in the discovery of seven distinct phage antibodies that bind to heat-killed forms of both bacteria.
  • The findings suggest that this approach could be an effective strategy for creating human monoclonal antibodies against these dangerous pathogens.

Article Abstract

Much effort has been devoted to the development of mouse monoclonal antibodies that react specifically with Burkholderia mallei and Burkholderia pseudomallei for diagnostic and/or therapeutic purposes. Our present study focused on the screening of a phage-displayed nonimmune human single-chain Fv (scFv) antibody library against heat-killed B. mallei and B. pseudomallei for the generation of human scFv antibodies specific to the two pathogenic species of bacteria. Using two different panning procedures, we obtained seven different scFv phage antibodies that interacted with the heat-killed whole bacterial cells of B. mallei and B. pseudomallei. Our results demonstrate that panning of a human scFv antibody library against heat-killed whole bacterial cells may provide a valuable strategy for developing human monoclonal antibodies against the highly pathogenic bacteria.

Human pluripotent stem cells (hPSCs) can be differentiated in vitro to an increasing number of mature cell types, presenting significant promise for addressing a wide range of diseases and studying human development. One approach to further enhance stem cell differentiation methods would be to coordinate multiple inducible gene or protein switches to operate simultaneously within the same cell, with minimal cross-interference, to precisely regulate a network of lineage-specifying transcription factors (TFs) to guide cell fate decisions. Therefore, in this study, we designed and tested various mammalian gene and protein switches responsive to clinically safe small-molecule inhibitors of viral proteases.

Background: The adoptive cell transfer (ACT) of T cell receptor (TCR)-engineered T cells targeting the HLA-A2-restricted epitope NY-ESO-1 (A2/NY) has yielded important clinical responses against several cancers. A variety of approaches are being taken to augment tumor control by ACT including TCR affinity-optimization and T-cell coengineering strategies to address the suppressive tumor microenvironment (TME). Most TCRs of clinical interest are evaluated in immunocompromised mice to enable human T-cell engraftment and do not recapitulate the dynamic interplay that occurs with endogenous immunity in a treated patient.

Background: Granzyme B (GrB) is a key effector molecule, delivered by cytotoxic T lymphocytes and natural killer cells during immune surveillance to induce cell death. Fusion proteins and immunoconjugates represent an innovative therapeutic approach to specifically deliver a deadly payload to target cells. Epithelial membrane protein-2 (EMP2) is highly expressed in invasive breast cancer (BC), including triple-negative BC (TNBC), and represents an attractive therapeutic target.

The hERG1 potassium channel conducts the cardiac repolarizing current, IKr. hERG1 has emerged as a therapeutic target for cardiac diseases marked by prolonged actional potential duration (APD). Unfortunately, many hERG1 activators display off-target and proarrhythmic effects that limit their therapeutic potential.

Designing artificial enzymes for in vivo catalysis presents a great challenge due to biomacromolecule contamination, poor biodistribution, and insufficient substrate interaction. Herein, we developed single-chain polymeric nanoparticles with Cu/N-heterocyclic carbene active sites (SCNP-Cu) to function as peroxidase mimics for in vivo catalysis and chemo-dynamic therapy (CDT). Compared with the enzyme mimics based on unfolded linear polymer scaffold and multichain cross-linked scaffold, SCNP-Cu exhibits improved tumor accumulation and CDT efficiency both in vitro and in vivo.
