Affinity Discrimination in B cells in Response to Membrane Antigen Requires Kinetic Proofreading [PDF]

arXiv, 2010
B cells signaling in response to antigen is proportional to antigen affinity, a process known as affinity discrimination. Recent research suggests that B cells can acquire antigen in membrane-bound form on the surface of antigen-presenting cells (APCs), with signaling being initiated within a few seconds of B cell/APC contact.

Bacteria‐Derived Extracellular Vesicle as A “Trojan Horse” for Selective M1 Macrophage‐Targeting in A Multi‐Cellular Entanglement Environment

Advanced Functional Materials, EarlyView.
The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

Do postoperative infectious complications really affect long‐term survival in colorectal cancer surgery? A multicenter retrospective cohort study

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 110-120, January 2023., 2023
This multicenter retrospective cohort study suggested that postoperative infection (PI) after curative colorectal surgery (CRC) is associated with impaired oncological outcomes. Strategies to prevent PI and implement appropriate postoperative treatment may improve the quality of care and oncological outcomes in patients undergoing curative CRC surgery.

Integrating influenza antigenic dynamics with molecular evolution [PDF]

arXiv, 2013
Influenza viruses undergo continual antigenic evolution allowing mutant viruses to evade host immunity acquired to previous virus strains. Antigenic phenotype is often assessed through pairwise measurement of cross-reactivity between influenza strains using the hemagglutination inhibition (HI) assay.

A stochastic individual-based model to explore the role of spatial interactions and antigen recognition in the immune response against solid tumours [PDF]

, 2019
Spatial interactions between cancer and immune cells, as well as the recognition of tumour antigens by cells of the immune system, play a key role in the immune response against solid tumours. The existing mathematical models generally focus only on one of these key aspects.

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

Advanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Bioprinting Perfusable and Vascularized Skeletal Muscle Flaps for the Treatment of Volumetric Muscle Loss

Advanced Healthcare Materials, EarlyView.
Volumetric muscle loss (VML) due to trauma or surgery, often leads to physical impairments. Traditional treatments rely on autologous flaps, limited by muscle availability often leading to donor site morbidity. This study presents multimodal bioprinting as an innovative approach for fabricating vascularized muscle flaps with 3D‐printed macrovessels ...

AIE‐based drug/gene delivery system: Evolution from fluorescence monitoring alone to augmented therapeutics

Aggregate, Volume 3, Issue 6, December 2022., 2022
The aggregation‐induced emission luminogens (AIEgens) propel the development of drug and gene delivery systems. The lit‐up AIEgens first serve for real‐time monitoring of the delivery processes and evaluation of therapeutic responses of drug/gene. The delicate design of AIEgens to form high‐level structural carrier remarkably enhances the delivery ...

Dynamics-based peptide-MHC binding optimization by a convolutional variational autoencoder: a use-case model for CASTELO [PDF]

arXiv, 2020
An unsolved challenge in the development of antigen specific immunotherapies is determining the optimal antigens to target. Comprehension of antigen-MHC binding is paramount towards achieving this goal. Here, we present CASTELO, a combined machine learning-molecular dynamics (ML-MD) approach to design novel antigens of increased MHC binding affinity ...
