B. include macrophages. C. engulf and modify antigen to be more immunogenic. D. hold and present processed antigen on their cell membrane surface. E. All of the choices are correct. Cells such as macrophages can process foreign antigens and attach them to their cell surface in order to assist in activation of T cells. Cells that have this function are called: antigen-presenting cells Phagocytic cells that digest a pathogen, then insert a bit of pathogenic antigen on their cell membrane, are described as being _____ cells.

Created by Sal Khan.Watch the next lesson: https://www.kha Antigen presentation is a vital immune process that is essential for T cell immune response triggering. Because T cells recognize only fragmented antigens displayed on cell surfaces, antigen processing must occur before the antigen fragment, now bound to the major histocompatibility complex (MHC), is transported to the surface of the cell, a process known as presentation, where it can be We will now take a look at antigen-presenting cells (APCs), which include dendritic cells, macrophages, and B-lymphocytes.APCs express both MHC-I and MHC-II molecules and serve two major functions during adaptive immunity: (1.) they capture and process antigens for presentation to T-lymphocytes, and (2) they produce signals required for the proliferation and differentiation of lymphocytes. Antigen presentation with MHC II is essential for the activation of T cells. Antigen-presenting cells (APCs) primarily ingest pathogens by phagocytosis, destroy them in the phagolysosomes, process the protein antigens, and select the most antigenic/immunodominant epitopes with MHC II for presentation to T cells. Dendritic cells (DCs), together with monocytes and macrophages, comprise the mononuclear phagocyte system.. DCs are professional antigen-presenting cells.

(2013). B cells that have surface immunoglobulin molecules with specificity for the antigen also participate by binding the antigen, processing it and presenting it to the CD4 T cells. Antigen presentation comprises other events besides processing of the antigen and formation of the peptide–MHC complex.

Projection of antigen presenting antigens effectively present them to get your visit has its occurrence and mechanisms. Antigen, substance that is capable of stimulating an immune response, specifically activating lymphocytes, which are the body’s infection-fighting white blood cells. Upon encountering their cognate antigen on SSMs, B cells become less motile and more dendritic.
