Does A Cell Know Friend From Foe

The topic i am going to be writing about today is how does a cell know friend from foe.

This relates back to what we have learned in bio as i am going to explain very soon. The 3 most important facts about how cell know friend from foe. First, allorecognition, Second amoeba cells and third tgr protein system. These are the 3 most important facts about how cells tell each other apart and know what to attack and what not to.

First, Allorecognition is a very research active subject. Allorecognition is immune cells using a system called major histocompatibility complex (MHC) to know which cells belong to the body and which are foreign. Brain cell,skin cells and nearly all our other cell in our body have (MHC) proteins on their outer surfaces.

When amoeba cells have a good amount of food they work as unicellular organisms when they are low on food they combine with their close relatives. Amebas use two sets of proteins to TgrB1 and TgrC 1 these protein are there so other cells can recognize cells from the same strain. So basically these proteins allow the cells to aggregate and combine and lock TgrB1 proteins to TgrC 1 proteins. Shaulsky think that when these proteins combine they make a cascade of signals that tell the cell whether or not to get together with a close relative to it own proteins. This all relates to biology and what we learned about but we are just going more in depth about what a cell does and what amebas do and how they would interact with each other and know whats friend from foe. They use proteins which in biology we have learned about but this is more in depth about how the cells can truly use proteins to help it self in determining what cells ar friend from foe. So it says how important proteins are in you system to keep everything running
