The fractional cell kill is a mathematical expression describing the rate at which a certain population of cells is reduced to a fraction of itself. We investigate the mathematical function that governs the rate at which a solid tumor is lysed by a cell population of cytotoxic lymphocytes. We do it in the context of enzyme kinetics, using geometrical and analytical arguments. We derive the equa...
Antimicrobial peptides (AMPs) are gaining attention as substitutes for antibiotics in order to combat the risk posed by multi-drug resistant pathogens. Several research groups are engaged in design of potent anti-infective agents using natural AMPs as templates. In this study, a library of peptides with high sequence similarity to Myeloid Antimicrobial Peptide (MAP) family were screened using p...
This protocol describes two biological assays to evaluate pathogenicity of Burkholderia cepacia complex (Bcc) strains against the nematode Caenorhabditis elegans. Specifically, these two assays allow one to identify if the under-investigated Bcc strains are able to kill the nematodes by intestinal colonization (slow killing assay, SKA) or by toxins production (fast killing assay, FKA). The prin...
Adoptive therapy with chimeric antigen receptor (CAR) T cells shows great promise clinically. However, there are important aspects of CAR-T-cell biology that have not been explored, particularly with respect to the kinetics of activation, immune synapse formation, and tumor cell killing. Moreover, the effects of signaling via the endogenous T-cell receptor (TCR) or CAR on killing kinetics are u...
In vitro synergism and killing kinetics studies of penicillin in combination with gentamicin were performed with group B streptococci recently isolated in Belgium. The expected accelerated killing was not observed when compared with penicillin alone. D 2005 Elsevier B.V. All rights reserved.
