MHC doesn't "recognize" bacteria or anything. It's job is simply take up the broken peptides. These peptides can be originally from a virus, bacteria, or from the cell itself (self). It will take these antigen that it can bind to and bring it to the cells surface. Your adaptive immunity cells (B and T cells) job is to "see" what the MHC has to offer and identify it as self (leave alone) or as foreign (need to destroy).
What else can I help you with?
The specific foreign substances that an individuals immune system has the ability to recognize and resist is detemined by?
The immune system's ability to recognize and resist specific foreign substances is determined by the unique set of proteins on the surface of cells called major histocompatibility complex (MHC) molecules. MHC molecules present antigens to immune cells, which stimulate the immune response. The immune system can only respond to antigens that are recognized by MHC molecules.
A marker molecule on a cell that the immune system uses to recognize a pathogen?
The major histocompatibility complex (MHC) molecules are marker molecules on cells that the immune system uses to recognize pathogens. MHC molecules present fragments of pathogens on the cell surface to alert immune cells to the presence of the pathogen. This helps the immune system to target and eliminate infected cells.
Does thymic selection destroy MHC molecules?
Thymic selection does not destroy major histocompatibility complex (MHC) molecules. Instead, it helps in the development of T cells by allowing them to recognize self-MHC molecules and self-antigens to ensure self-tolerance and proper immune function.
Four of the five cells listed - viruses cells - MHC markers - cancer cells - bacteria - dead cells - are targets of the immune system - Select the exception?
MHC markers- which are proteins that present or "show" antigens like bacteria to other immune cells. Instead of being targets, they are helper proteins of the immune system.
What is the role of MHC?
Major Histocompatibility Complex (MHC) molecules play a crucial role in the immune system by presenting antigens to T cells. This helps T cells identify and respond to foreign invaders such as viruses or bacteria. MHC molecules are essential for adaptive immune responses and play a key role in determining compatibility for organ transplants.
How do phagocytes recognize foreign cells or bacteria?
Lymphocytes are part of the human body's innate immune system. Natural killer cells seek out and destroy foreign cells by distinguishing surface molecules of major histocompatibility complex class.
The MHC is important in a T cell's ability to?
The major histocompatibility complex (MHC) is important in a T cell's ability to recognize antigens presented by antigen-presenting cells. This recognition is crucial for initiating an immune response and coordinating the functions of different immune cells. Deficiencies in MHC expression or function can impact the ability of T cells to mount an effective immune response.
What does the medical abbreviation MHC mean?
MHC = major histocompatibility complex What makes up MHC are HLA's (human leukocyte antigens), which there are subclasses for.
How does the injection of a vaccine made from killed bacteria bring immunity to a human?
The immune system does not recognize the killed bacteria, and cannot recognize that the bacteria are killed, so it begins to produce antibodies for it just as it would if the bacteria were alive.
When was MHC Krylya Sovetov created?
MHC Krylya Sovetov was created in 2008.
How does involvement of MHC 1 and MHC 2 help immune system?
MHC IMHC I is present in all cells except red blood cells (they lack nuclei). MHC I will present an intravesicular antigen to the cells surface for it to be identified as self or foreign by your adaptive immunity cells.MHC IIMHC II is present in professional antigen presenting cells which include: macrophages, B cells and dendritic cells. These cells will engulf bacteria, soluble proteins, viruses, etc. Whatever was taken into the cell becomes processed in the increasingly acidic endosome that eventually will cut the antigen into peptides. MHC II transported from the ER will meet up with this endosome and the peptides will bind to MHC II for it to eventually present on the cells surface.
What are two types of bacteria that scientist recognize?
germs
