Provide the following cells involved in immune system with at least one function or capabilities listed here: a) can be converted to memory cell for immunity . b) involved in immune-cytotoxic function. c)involved in innate immune system. D) involved in humoral immune system. E) secret antibodies. f) major target of AIDS virus. G)antigen -presenting cells or APCs. H) carry B cell receptors or BCR I) carry T cell receptors or TCR. J) express class 1 MHC molecules or major histocompatibility molecule. K) express class II MHC molecules.
1- macrophage.
2-dendritic cells
3- B-lymphocytes
4- plasms cells
5-T-lymphocytes express a glycoprotein called CD4
6- T-lymphocytes express a glycoprotein called CD8
7-helper T cell
8- T-lymphocytes
Explanation / Answer
1-MACROPHAGE
a large white somatic cell, occurring primarily in animal tissue and within the blood, that ingests foreign particles and infectious microorganisms by phagocytosis.
2-DENDRITIC CELLS
Dendritic cells (DCs) are skilled antigen-presenting cells situated within the skin, tissue layer and lymphoid tissues. Their main operate is to process antigens and present them to T cells to push immunity to foreign antigens and tolerance to self antigens. They conjointly secrete cytokines to control immune responses.
3- B-LYMPHOCYTES
A type of white somatic cell that produces antibodies. B lymphocytes are a part of the system and develop from stem cells within the bone marrow. They function in the humoral immunity component of the adaptive immune system by secreting antibodies.
4- PLASMA CELLS
A type of white blood corpuscle that produces and secretes antibodies. A plasma cell could be a totally differentiated, mature WBC within the B lymphocyte lineage. like most cell varieties, plasma cells will change to allow rise to cancer. plasma cell malignancies embrace tumor, myeloma etc.
5-CD4
These cells are referred to as CD4+ T cells as a result of they categorical the CD4 conjugated protein on their surfaces. CD4+ T helper cells are white blood cells that are an important part of the human system. ... they're known as helper cells because one amongst their main roles is to send signals to alternative kinds of immune cells, as well as CD8 killer cells, that then destroy the infectious particle.
6- CD8
CD8+ T cells are characterised by a CD8 protein on their cell surface that functions to acknowledge and bind infected cells. CD8+ T-cell or killer T cell could be a T cell (a form of white blood cell) that kills cancer cells, cells that are infected (particularly with viruses), or cells that are broken in alternative ways.
7- HELPER T CELL
Helper T cells don't directly kill infected cells, as cytotoxic T cells do. Instead they assist activate cytotoxic T cells and macrophages to attack infected cells, or they stimulate B cells to secrete antibodies.
8- T-LYMPHOCYTES:-
T lymphocyte, may be a kind of white cell that plays a central role in cell-mediated immunity. T cells are thus known as because they're preponderantly made within the thymus. They recognise foreign particles (antigen) by a surface expressed, extremely variable, T cell receptor (TCR).
