If antigens are foreign substances then why are the proteins on red blood cells that are responsible for blood type identification called antigens when they're something inherent of the person?
That's a GREAT question! They are called antigens, because even though they have no reaction to individual whose blood is, they can have a reaction in someone else. For example, if you give a person with blood type A, B blood, the blood type A person will react to those B antigens.
@@DrVanessa so why is a person born with a foreign substance (antigen)? What is this specific antigen that is affecting these particular species of neanderthals?

@@carlorealist6907 a person isn’t born with a foreign antigen. Foreign antigens are those things that the body does not recognize as it’s own proteins (this is a process the immune system goes through as it develops ). Therefore, foreign antigens come from outside the body.
@@carlorealist6907 if you are referring to red blood cell antigens, they are not foreign to the individual themselves, but only to individuals who don’t have them.
@@DrVanessa Thank you so much, doc! Please also do the Complement System Cytokines for better understanding. Thank you so much, doc. It really helps me understand our topic!!!
So you have type O. This is not a good or bad thing, just what makes it blood type what it is and let’s you know who can receive blood from or give blood to.
That's so true! There are many cells including red blood cells that have antigens on their surface. This was a basic video describing the antigen/antibody relationship. However, I describe blood groups in detail in this video (including antigens on their cell surface). This was a precursor to that video. th-cam.com/video/p6xoRJ3rWpQ/w-d-xo.html
I’ve been trying to find out how antigens are weakened and deactivated, but I haven’t found anything. I know this video doesn’t relate to my question, however, I thought you may be able to help me.
I’m unsure if your question. Do you mean by the antibodies? When an antibody binds to an antigen, it neutralizes it, so it can no longer do the job it was supposed to. Does that help? If not, please try to reword your question. The antigen by itself does not get weakened or deactivated unless the immune system interferes.
@@simranbuttar3618 Not all vaccines use antigens directly. It really depends on the vaccine. Check out this video I made on vaccines, it explains what types of vaccines are made, even the new mRNA type.

Antigens are things that the body recognizes as foreign. We usually think of them as pathogens, viruses, bacteria, etc. that come into the body, that is not a self protein. However, as you pointed out, antigens are present on RBCs. This can make it confusing. This is because the body CAN recognize them as foreign, and have antibodies against them. The difference is, the person who actually has the antigen on their RBC, it is really not an antigen to them because it will be a self protein, but can be an antigen to someone else. This was all found and named before our understanding of the immune system and antibodies and antigens. But, because some people can recognize those cell surface markers as foreign, they have been called antigens. Check out the video I link here, that will show you more. Hopefully, that will help clear up the confusion. And, reach out if you have any more questions! th-cam.com/video/p6xoRJ3rWpQ/w-d-xo.html
That is just a natural phenomenon. Normally, our bodies have to make antibodies towards antigens that enter our body. However, when pertaining to blood types, our bodies naturally make these opposite antibodies from the beginning. For example, if you are Type A blood you make anti-type B antibodies from the beginning. This is just naturally occurring. It is also why it is very dangerous to receive the wrong type of blood as the reaction will be immediate.
Thank u! it was a nice presentation. ❣ Actually I have a doubt ..it said that antigen is a foreign substance which means they are not supposed to be in the body but WHY RBC has antigen??? That's mean RBCs are not supposed to be in our body😮???
Good question! Antigens are foreign to the body and elicit and immune response. RBC antigens are confusing because obviously some people have some of them or none, depending on blood type. A RBC antigen is not foreign to the person who has it, but is foreign to the person who doesn’t. Meaning, if someone is given the wrong blood type, an immune response will happen and cause agglutination. This is not good. I have another video on ABO blood typing. Check it out because I go through it in more detail and I think it may help you to make more sense of it.
Maybe not. Testing positive for the antigen means you have the virus or bacteria testing for. Eventually, yes, you will test positive for antibodies, but your body needs time to make them which takes weeks. Usually at that point when antibodies are actually made, you won’t test positive for antigen, but it is possible.
@@kevinwu3110 IgM antibodies are made first by activated B cells, then there is a class switch to IgG. IgG is the most common and what confers immunity. IgG is a monomer while IgM is a pentamer.
Hi! I worked on some settings, if you add CC (closed captions), then you should be able to auto generate them into Hindi. It seems to only work on my laptop, not the phone settings. If you have a computer, see if that may work for you! I’d love to hear feedback. Thank you!
