Resting dendritic cells
WebDec 5, 2013 · Author Summary Current antiretroviral drugs significantly prolong life and reduce morbidity but are unable to cure HIV. While on treatment, the virus is able to hide in resting memory T cells in a silent or “latent” form. These latently infected cells are rare and thus are hard to study using blood from HIV-infected individuals on treatment. Therefore, … WebMay 1, 2002 · Dendritic cells (DCs) are recognized as the key antigen-presenting cells (APCs) controlling the initiation of T cell–dependent immune responses.1 DCs not only are the most potent APCs for activation of resting T cells, but can also regulate the type of response made, dictating the cytokines expressed by responding T cells.2 Furthermore, …

WebAug 8, 2011 · Ferlazzo G, Tsang ML, Moretta L, Melioli G, Steinman RM, Munz C . Human dendritic cells activate resting natural killer (NK) cells and are recognized via the NKp30 receptor by activated NK cells. WebMar 20, 2009 · The effect of adenosine mediated suppression of immune cell activation has long been an important topic of study. While the protective benefits of such a signaling mechanism are well recognized, there remains a question as to how dendritic cells (DCs) bypass the high levels of adenosine during tissue stress and infection, and become fully …
WebWithin mucosal environments, APCs play a key regulatory role via sampling and presenting antigen in a form recognizable by the immune system. Among APC populations present within the mucosae, dendritic cells (DCs) 1 are unique in being able to efficiently stimulate primary immunity. Previous studies from our (1, 2) and other (3, 4) laboratories have … WebAug 29, 2024 · Here the authors describe the roles of dendritic cells in the tumour microenvironment and the different ...

WebDendritic cells (DCs) are immune cells that effectively link the innate and adaptive arms of the immune system. They are considered a professional antigen-presenting cell population because of their unique capacity to induce the activation and differentiation of naive T lymphocytes. Included in this function is the ability to initiate ... WebT cells recognizing self proteins exist without causing autoimmunity in healthy individuals. These autoreactive T cells are kept in check by peripheral tolerance. Using a model for peripheral CD8(+) T cell tolerance resulting from antigen presentation by resting dendritic cells in vivo, we show here …
WebDec 1, 2006 · Dendritic cells (DCs) are antigen-presenting cells with a unique ability to induce primary immune responses. They are present in trace amounts in most tissues, but they are particularly abundant and act as sentinels in organs providing an environmental interface, such as the skin, the respiratory system, and the gastrointestinal tract.
WebMay 1, 2003 · Dendritic cells (DC) are inducers of immune responses par excellence. They also seem responsible for the induction of peripheral T cell tolerance. To investigate these opposite functions of DC, we generated a Cre/LoxP-based system that allows inducible antigen presentation by DC in vivo. This enables us to study the immunogical … proper backgroundWebFeb 28, 2007 · Resting respiratory tract dendritic cells preferentially stimulate T helper cell type 2 (Th2) responses and require obligatory cytokine signals for induction of Th1 immunity.
