The chromosomal locus encoding the early secreted antigenic target, 6 kDa (ESAT-6) secretion system 1 of Mycobacterium tuberculosis, also referred to as "region of difference 1 (RD1)," is absent from Mycobacterium bovis bacillus Calmette-Guerin (BCG). In t ...
New generation vaccines, which are subunit vaccines, have considerably improved safety profiles, but are often poorly immunogenic, especially when administered through mucosal routes. Also, the diversity of the mechanisms of action of infectious pathogens ...
Dendritic cells (DC) are potent inducers of immune responses. DC have been shown to infiltrate tumors, but very little is known about the functional status of these naturally occurring tumor-infiltrating DC (TIDC). In this study, the status and function of ...
Understanding how human genetic variation impacts individual response to immunogens is fundamental for rational vaccine development. To explore host mechanisms involved in cellular immune responses to the MRKAd5 human immunodeficiency virus type 1 (HIV-1) ...
We introduce the concept of the NutriChip, a miniaturized artificial human gastrointestinal tract (GIT) for investigating the potential of immuno-modulatory function of dairy food. More specifically, we are investigating the effect of digested milk on immu ...
Lymphatic vessels transport interstitial fluid, soluble Ag, and immune cells from peripheral tissues to lymph nodes (LNs), yet the contribution of peripheral lymphatic drainage to adaptive immunity remains poorly understood. We examined immune responses to ...
Pore-forming toxins (PFTs) are the most common class of bacterial protein toxin and are important for bacterial pathogenesis. Recent studies have shown that the previous model stating that epithelial cells lyse in response to these toxins and have no defen ...
Vaccines aim to protect against or treat diseases through manipulation of the immune response, promoting either immunity or tolerance. In the former case, vaccines generate antibodies and T cells poised to protect against future pathogen encounter or attac ...
Cell response to extracellular cues is often driven by gradients of morphogenetic and chemotactic proteins, and therefore descriptions of how such gradients arise are critical to understanding and manipulating these processes. Many of these proteins are se ...
T lymphocytes (T cells) are key components of the adaptive immune system. These cells are able to recognize an enormous variety of pathogens thanks to the great specificity of their trans-membrane proteins, the T cell receptors (TCRs). TCR diversity is cre ...
