Gene induction during differentiation of human monocytes into dendritic cells: an integrated study at the RNA and protein levels [PDF]
Changes in gene expression occurring during differentiation of human monocytes into dendritic cells were studied at the RNA and protein levels. These studies showed the induction of several gene classes corresponding to various biological functions ...

Resilient Biophysical Phenotype of Memory CD4 + T Cells in Long‐Lived Mice
Aging is associated with increased stiffness and reduced migratory capacity of memory CD4+ T cells; however, these biophysical declines do not persist in exceptionally long‐lived mice. Instead, long‐lived individuals preserve T cell mechanics, migration and intracellular architecture, supporting mechanical resilience as a hallmark of successful immune ...

Inflammatory Mediators Both Directly and Indirectly Promote Microglial Proliferation
– CSF2, IL3, and TNFɑ directly promote microglial proliferation. – Neuron‐secreted factors suppress microglial proliferation. – IL1 cytokines promote CSF2 release from astrocytes, which promotes microglial proliferation. ABSTRACT Microglia—the predominant immune cell of the central nervous system (CNS)—possess an astounding capacity for proliferation ...

CD1: A Singed Cat of the Three Antigen Presentation Systems [PDF]
Contrary to general view that the MHC Class I and II are the kapellmeisters of recognition and response to antigens, there is another big player in that part of immunity, represented by CD1 glycoproteins. In contrast to MHC Class I or II, which present peptides, CD1 molecules present lipids.

The Role of Invariant Natural Killer T Cells in Dendritic Cell Licensing, Cross-Priming, and Memory CD8+ T Cell Generation [PDF]
New vaccination strategies focus on achieving CD8+ T cell (CTL) immunity rather than on induction of protective antibody responses. While the requirement of CD4+ T (Th) cell help in dendritic cell (DC) activation and licensing, and in CTL memory ...

Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?
ABSTRACT The enteric nervous system (ENS), a key component of the gut–brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)—a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or ...

Recognition of microbial glycolipids by Natural Killer T cells
T cells can recognize microbial antigens when presented by dedicated antigen-presenting molecules. While peptides are presented by classical members of the Major Histocompatibility (MHC) family (MHC I and II), lipids, glycolipids and lipopeptides can be ...

Class I dependence of the development of CD4+ CD8- NK1.1+ thymocytes. [PDF]
A small subset of functionally active CD4+ CD8- thymocytes express the NK1.1 marker, as do most CD4-CD8- NK1.1+ thymocytes. Previous studies have failed to implicate a role for major histocompatibility complex (MHC) or related molecules in the selection ...

Metabolic changes in immune cells direct the phenotype and function of the host immune system. Smart nanomaterials must target metabolic pathways to direct immune cell fate. This study reports the fabrication and first application of germanane quantum dots (GeHQDs) to modulate inflammation in vitro and in vivo.
