What do T-cells check each cell for?
Most excellent question! The T cell checks cells to see if the antigens that are presented on MHC class I molecules are self or foreign. If it is self, then it is left alone. Otherwise it will decide that it needs to destroy.
What do white blood cells use to engulf and destroy bacteria that the glycoproteins recognize as not self?
White blood cells use a process called phagocytosis to engulf and destroy bacteria that are recognized as not-self by their glycoproteins. During phagocytosis, the white blood cell engulfs the bacteria, forms a phagosome, and then fuses it with lysosomes to break down the bacteria using enzymes.
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.
Do b cells destroy cancer cells?
B cells play a role in the immune response against cancer by producing antibodies that can help target cancer cells for destruction by other immune cells. They do not directly destroy cancer cells themselves, but help to coordinate the immune system's response against cancer.
How is cell-to-cell recognition important?
It is important, for example, in the sorting of cells into tissues and organs in an animal embyro. It is also the basis for the rejection of foreign cells by the immune system, an important line of defense in vertebrate animals.

Is an egg made of cells?
Egg it self is cell.

How are tumor cells diffrent from normal cells?
Normal cells have a self-destruct mechanism. This means that at any time, when a cell realises it's not functioning correctly and there's nothing it can do to repair itself and correct the mistake. It'll destroy itself. The incorrect funtionning of a tumor cell however is a defect in this self-destruct mechanism. So the cell will never destroy itself even though it's not working correctly. Since cell division is basically making another copy of the mother cell, this defect is passed on to all cells that are produced from this mother cell and the error is never detected.
Can you describe how white blood cells destroy pathogen?
Dont no im trying to find out my self!! sorry!!
What is the difference between stem cells and progenitor cells?
The main difference between a stem cell and a differentiated cell is: A stem cell has the ability to self-renewel and also has the ability to differentiate(to become a tissue specific cell). But, a differentiated cell don't have the ability to self-renewel(moreover a stem cell get specialised to a differentiated cell).
Function of recognition proteins?
Recognition proteins are involved in identifying and binding to specific molecules or cells. They play a key role in immune responses, cell signaling, and cell-cell interactions. In the immune system, recognition proteins help differentiate between self and non-self molecules.
How does the immune system fight a virus?
T cells compare non-self antigens to HLA (human leukocyte antigens) molecules with proteins the system already knows are its own. Your T-cells don't react to your HLA because of tolerance but are not tolerant to the HLA proteins of someone else. Thus, when there is a non-self system in your body (i.e.: after a transplant), your T-cells will begin a cell-mediated immune response against it, considering them foreign.
How does the immune system recognize its own body?
By recognizing self from non-self. Every cell in the body carries specific protein markers that are recognized by all immune cells so they do not attack self, at least when the system is operating well.
How a natural killer cells don't kill own or self cell because NK cells are non specific in nature?
Natural killer (NK) cells have receptors that recognize "self" proteins on healthy cells, preventing them from attacking these cells. These receptors help distinguish healthy cells from abnormal or infected cells. Additionally, healthy cells release molecules that send inhibitory signals to NK cells, further preventing them from attacking self cells.
Does mhc recognize bacteria?
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).
