Nanoparticles that activate complement in the absence of biological molecules are described. The nanoparticles are shown to specifically target antigen presenting cells in specifically in lymph nodes, without the use of a biological molecule for targeting. ...
The neurotransmitter noradrenaline (NA) plays a pivotal role in immune regulation. Here we used the selective neurotoxin N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP-4) to investigate the impact of central NA depletion on cytokine production by spleni ...
In the paracortex of the lymph node (LN), T zone fibroblastic reticular cells (TRCs) orchestrate an immune response by guiding lymphocyte migration both physically, by creating three-dimensional (3D) cell networks, and chemically, by secreting the chemokin ...
MHC-class II genes determine susceptibility in human type-1 diabetes. In their context, presentation of target antigen(s) results in autoimmunity and b-cell destruction. An animal model, in which human b-cell autoantigen(s) are presented to effector cells ...
The current state-of-art in 3D microfluidic chemotaxis device (mu FCD) is limited by the inherent coupling of the fluid flow and chemical concentration gradients. Here, we present an agarose-based 3D mu FCD that decouples these two important parameters, in ...
Polarized mature dendritic cells (DC) can activate cytolytic T-lymphocyte (CTL) responses and may be a more effective clinical strategy in DC-based cancer vaccines. A subset of mature DC can down-regulate the T-cell immune response through expression of in ...
Thymic stromal lymphopoietin (TSLP) is an interleukin (IL)-7-like cytokine, mainly expressed by epithelial cells, and key to the development of allergic responses. The well-documented involvement of TSLP in allergy has led to the conviction that TSLP promo ...
Detection of non-self RNA by TLRs within endosomes and by retinoic acid-inducible gene I (RIG-I)-like helicases in the cytosol is central to mammalian antiviral immunity. In this study, we used pathway-specific agonists and targeted delivery to address RNA ...
Intracellular pathogens like Shigella flexneri enter host cells by phagocytosis. Once inside, the pathogen breaks the vacuolar membrane for cytosolic access. The fate and function of the vacuolar membrane remnants are not clear. Examining Shigella-infected ...
Immunostimulatory RNA (isRNA) depending on sequence and structure can function as a ligand for Toll-like receptor (TLR) 7 and TLR8. Here we show that isRNA induces high levels of bioactive interleukin-12 in purified human monocytes, whereas purified natura ...
