What else can I help you with?
What blood type of blood has no anitgens?
O... O has no antigens, so it has antibodies for both A and B.
What do you exhibit when B cells encounter antigens and produce antibodies against them?
You exhibit Active Immunity when cells encounter anitgens and produce antibodies against them.
What has the author R E Gaensslen written?
R. E. Gaensslen has written: 'Procedures and evaluation of antisera for the typing of anitgens in bloodstains' -- subject(s): Analysis, Blood group antigens, Bloodstains 'Procedures and evaluation of antisera for the typing of antigens in bloodstains' -- subject(s): Antigens, Serum
Can o blood be transfused into h-h blood?
No, not safely. O blood has H anitgens but HH blood does not. HH blood type can only receive blood from other HH blood types. HH blood is not stored in blood banks. Also HH blood when tested to see if A B or O, tests as O, unless the lab or technician test further to check for H anitgens, something not routinely done.
What does the bodys line of defense do if you get rabies?
Well, you first get infected from a scratch or bite, then the infection spreads into the bloodstream, getting by the first line of defence. The second line of defence, would be the white blood cells. They try overcome or "swallow" the infection. the third line of defense, is the anitgens. If all else fails, your f*cked.
When small molecules bind to self cell-surface proteins what do they act as?
When small molecules bind to self cell-surface proteins, they can act as signaling molecules that trigger specific responses within the cell. This binding can also affect cell-cell interactions, influence cell adhesion, or regulate processes like growth and development.
Are anitgens proteins?
Yes. An antigen is a substance that stimulates an animal in order to produce an antibody reaction to counteract the substance by a specific binding antibody-antigen. Most of the times this antigen is a molecule of protein.
What does it mean to have o blood type?
People with Type O Blood are different than the other 3 major blood types, where as Type O lacks the anitgens on the red blood cell surface. Type O is known as the Universal Donor due to the fact that type O can give blood to all blood types but can not recieve any blood from the other blood types, only itself the type O.
How does ABO blood typing work?
in the ABO blood type, there are two main anitgens or agglutinogens, A and B. A type has the A antigen, B type B antigen, O none, and AB both the A and B antigen. Thus, O is a universal donor due to its lack of antigens and AB is a univeral reciepient due to the fact that it has both antigens. btw, antigens= complex sugar molecules attached to the membrane of RBCs
What is present in a vaccine to cause white blood cells to respond in this way?
A vaccination introduces killed/weakened pathogens or an antigen to the body. An antigen is anything that triggers an immune system response (generally a surface protein on a pathogen). In order to understand why this helps it is crucial to understand how the immune system operates: The body has two types of immunity "Cell-mediated" and "Humoral Immunity." Cell-mediated immunity is essentially a mob of Killer T Cells and a few others going around attacking pathogens and infected body cells. But the Humoral Response is the one we are concerned with for your question... Humoral Immunity is mediated by the secretion of antibodies from B lymphocytes. There are two main types of B lymphocytes, Memory Cells and and Plasma B Cells. Memory cells are randomly generated and stored mainly in lymph nodes. A human body which has never been exposed to a disease will have ONE of each Memory Cell 'hidden' in a lymph node. Each Memory Cell applies to ONE pathogen. The Memory Cell essentially tells other cells to do their jobs to fight an infection, not much will get done without it. Once a Memory Cell has been activated, it will continue to proliferate forever, even after the pathogen it fights is gone. In a very introductory level synopsis, if a pathogen breaks through the primary and secondary defenses of the body and it comes time for the real beats (the humoral response) to activate a very inefficient and time consuming process occurs in which an antigen presenting cell engulfs the pathogen and then seeks the specific Memory Cell in the lymphatic system. Now bear in mind (if the body ha snot yet been exposed to the disease) the cell is searching for ONE Memory Cell among 10 trillion body cells! With some sicknesses, it takes too long to find the Memory Cell and the patient could be terminal before it is found and the Humoral Response triggered. Now the old adage is "prevention is worth a pund of cure," and if it worked for my 7th grade English teacher it works for microbiology as well. The ultimate goal of a vaccination is to expose the body to severely weakened pathogens or purified anitgens, neither of which are likely to cause an adverse reaction. By doing this, a humoral response is triggered and the body seeks the proper Memory Cell, this cell then proliferates throughout the course of the patient's life and will be found much more quickly should it be needed to fight a real infection.
