If Our Immune System Knew We Had Eyes, We’d Go Blind!
As crazy as it may sound, this theory is real.
This theory is given by doctors and medical scientists.
As we know our eye is a delicate organ that is essential for vision. It is also a very vulnerable organ, as it is exposed to the outside world through the cornea. To protect the eye from infection and injury, the immune system has developed a number of specialized mechanisms.
One of these mechanisms is known as immune privilege.
Immune privilege:
Immune privilege is a state of reduced immune responsiveness in certain tissues and organs. This allows our eye to maintain a clear cornea and retina, which are essential for vision.
However, if the immune system were to become aware of our eye’s existence, this immune privilege could be lost. Without immune privilege, the immune system would attack our eye as a foreign invader. This would lead to inflammation and damage, which could ultimately result in blindness.
Why Would the Immune System Attack the Eyes?
Our immune system is designed to protect the body from infection and injury. It does this by identifying and destroying foreign invaders, such as bacteria, viruses, and cancer cells.
The immune system uses a variety of mechanisms to identify foreign invaders. One of these mechanisms is the use of antibodies. Antibodies are proteins that can bind to specific antigens, which are molecules that are found on the surface of foreign invaders.
Once an antibody has bound to an antigen, it triggers an immune response. This immune response can lead to the destruction of the foreign invader.
Our immune system also uses a variety of cells to identify and destroy foreign invaders. One of these cells is the T cell. T cells can recognize and destroy foreign invaders that have already infected the body’s cells.
How Could the Immune System Become Aware of the Eyes?
There are a number of ways in which the immune system could become aware of the eyes. One way is through injury. If the eye is injured, the immune system will respond to the injury by sending immune cells to our eye.
Another way in which the immune system could become aware of the eyes is through infection. If our eye is infected, the immune system will also respond by sending immune cells to the eye.
Finally, the immune system could become aware of the eyes through a process known as autoimmunity. Autoimmunity is a condition in which the immune system attacks the body's own tissues. There are a number of autoimmune diseases that can affect the eye, such as uveitis and optic neuritis.
Conclusion
The immune system is a powerful tool that protects the body from infection and injury. However, if our immune system were to become aware of our eye’s existence, it could attack our eye as a foreign invader. This would lead us to inflammation and damage, which could ultimately result in blindness.
Theory of why the immune system isn’t attacking our eyes right now
According to one theory, why the immune system does not attack our eyes is that the eyes have evolved to be invisible to the immune system. This is known as the immune privilege of the eye sounds crazy, doesn’t it?
The immune privilege of the eye is achieved through a number of mechanisms. One mechanism is the presence of a blood-retinal barrier. The blood-retinal barrier is a layer of cells that separates the bloodstream from the retina. This barrier prevents most immune cells from entering the retina.
Another mechanism that contributes to the immune privilege of the eye is the presence of a number of immune-suppressive molecules. These molecules help to suppress the immune response within the eye.
It is thought that the immune privilege of our eye is essential for our vision.
