Wafer‐Scale Integration of α‐quartz Thin Films toward Super High Frequency Piezoelectric bioNEMS for Chikungunya Virus Detection

Advanced Functional Materials, EarlyView.
Epitaxial piezoelectric α‐quartz/Si BioNEMS sensors, made using soft chemistry, effectively detect the Chikungunya virus. They have a mass sensitivity of 205 pg Hz−1 in liquid and can detect the virus at a limit of 9 ng mL−1. This development enables high‐frequency mass devices for point‐of‐care testing in healthcare and other electronic applications ...

T cells as antigen-presenting cells

Immunology Today, 1994
Human T cells express major histocompatibility complex (MHC) class II antigens and adhesion molecules characteristic of antigen-presenting cells (APCs), and recent in vitro and in vivo evidence supports an antigen-presenting function for T cells. In this guise, T cells provide downregulatory signals for the immune response by inducing anergy in T cells

Basophils as antigen presenting cells

Trends in Immunology, 2010
Recent reports demonstrate that basophils act as antigen presenting cells to drive Th2 and IgE responses against protease and protein allergens and helminth parasites. Through MHC class II-dependent cognate interactions with CD4(+) T cells in the context of co-stimulatory molecules, and through secretion of IL-4, IL-13 and thymic stromal lymphopoietin,

Antigen presenting cells

Immunologic Research, 1989
A great deal has been learned over the past few years regarding the molecular biology of antigen presentation. These discoveries have been possible in part because of acquisition of protein sequencing data regarding class I and class II MHC molecules and in part because of X-ray crystallographic analysis of the three-dimensional structures of these ...

Antigen Presentation to B Cells

Trends in Immunology, 2016
Unlike T cells that recognize digested peptides, B cells recognize their cognate antigen in its native form. The B cell receptor used in recognition can also be secreted to bind to antigens and initiate multiple effector functions such as phagocytosis, complement activation, or neutralization of receptors.

A class of γδ T cell receptors recognize the underside of the antigen-presenting molecule MR1

Science, 2019
A different way for γδ T cells to bind The ligands bound by γδ T cell receptors (TCRs) are less well characterized than those of their αβ TCR cousins, which are antigens presented by major histocompatibility complex (MHC) and related proteins.
