Adaptation of Prokaryotic Toxins for Negative Selection and Cloning-Independent Markerless Mutagenesis in Streptococcus Species [PDF]

open access: yesmSphere, 2023
The Streptococcus mutans genetic system offers a variety of strategies to rapidly engineer targeted chromosomal mutations. Previously, we reported the first S. mutans negative selection system that functions in a wild-type background.

Oral delivery of peptides and proteins: pharmacokinetic boundaries, negative selection, and route triage [PDF]

open access: yesFrontiers in Drug Delivery
Oral delivery of peptides and proteins has been pursued for over a century due to its noninvasive nature. Despite sustained innovation across multiple technological generations—such as enteric coatings, enzyme inhibitors, permeation enhancers ...

Manufacture of CD22 CAR T cells following positive versus negative selection results in distinct cytokine secretion profiles and γδ T cell output [PDF]

open access: yesMolecular Therapy: Methods & Clinical Development
Chimeric antigen receptor T cells (CART) have demonstrated curative potential for hematological malignancies, but the optimal manufacturing has not yet been determined and may differ across products.

Is T Cell Negative Selection a Learning Algorithm? [PDF]

open access: yesCells, 2020
Our immune system can destroy most cells in our body, an ability that needs to be tightly controlled. To prevent autoimmunity, the thymic medulla exposes developing T cells to normal “self” peptides and prevents any responders from entering ...

A Clone Selection Based Real-Valued Negative Selection Algorithm [PDF]

open access: yesComplexity, 2018
Excessive detectors, high time complexity, and loopholes are main problems which current negative selection algorithms have face and greatly limit the practical applications of negative selection algorithms.

Sampled Value Attack Detection for Busbar Differential Protection Based on a Negative Selection Immune System

open access: yesJournal of Modern Power Systems and Clean Energy, 2023
Considering a variety of sampled value (SV) attacks on busbar differential protection (BDP) which poses challenges to conventional learning algorithms, an algorithm to detect SV attacks based on the immune system of negative selection is developed in ...

Thymic Microenvironment: Interactions Between Innate Immune Cells and Developing Thymocytes

open access: yesFrontiers in Immunology, 2022
The thymus is a crucial organ for the development of T cells. T cell progenitors first migrate from the bone marrow into the thymus. During the journey to become a mature T cell, progenitors require interactions with many different cell types within the ...

Antibody Dynamics Simulation—A Mathematical Exploration of Clonal Deletion and Somatic Hypermutation

open access: yesBiomedicines, 2023
We have employed mathematical modeling techniques to construct a comprehensive framework for elucidating the intricate response mechanisms of the immune system, facilitating a deeper understanding of B-cell clonal deletion and somatic hypermutation.
