What is the cure in hepatitis b surface antigen?
At present, there is no cure for Hepatitis B. There is a vaccine that will prevent it, however.
What means Anti-HBs non reactive?
Anti Hbs is a titer measuring antibodies to the hepatitis B surface antigen. Anti Hbs reactive means that you are immune to hepatitis B, either due to previous immunization or recovery from hepatitis B.
Hepatitis b patients saliva is also dangerous like patients blood?
The hepatitis B virus can be present in an infected persons' saliva. However, it does not appear to be the case that this means an infected patients' saliva is also dangerous, like their blood is.
If the anti-A antibody causes blood to coagulate which antigen would be present on the red blood cells?
a
In serum antigen present or not?
Yes, serum does contain antigens
What does the medical abbreviation HBs Ag Non-reactive mean?
You do not have Hepatitis Surface B antigens present. This can mean you do not have Hep B or if you have had vaccinations and are getting tested within months of the shots, they have not produced sufficient immunity. (If the titer is done years after the immunization, the levels may be non-reactive, but the body still may produce an anamnestic response demonstrating that low titer levels years after immunization are not an effective indicator of immune status.)
What immunity results when millions of memory b cells remain in the body?
Memory b cells provide long term immunity for a specific disease or antigen. As an example a vaccination for hepatitis A provides memory b cells that will attack the disease when it is present and remove it.
What does the presence of the Rh antigen mean?
Rh antigen, which is also called D antigen, indicates if the blood type is positive or negative. The presence of this antigen indicates the patient is Rh positive, the absence of this antigen reflects a blood type of Rh Negative. For example, if a person is O Positive, the Rh antigen is present.
How does involvement of MHC 1 and MHC 2 help immune system?
MHC IMHC I is present in all cells except red blood cells (they lack nuclei). MHC I will present an intravesicular antigen to the cells surface for it to be identified as self or foreign by your adaptive immunity cells.MHC IIMHC II is present in professional antigen presenting cells which include: macrophages, B cells and dendritic cells. These cells will engulf bacteria, soluble proteins, viruses, etc. Whatever was taken into the cell becomes processed in the increasingly acidic endosome that eventually will cut the antigen into peptides. MHC II transported from the ER will meet up with this endosome and the peptides will bind to MHC II for it to eventually present on the cells surface.
What is a histocompatibility antigen?
Histocompatibility antigens are molecules on the surface of all cells in the body. The specific types of histocompatibility antigens present on a person's cells determine their identity and distinguish each person. They are a "fingerprint."
Why does a patient's body accept the blood by transfusion despite the fact that the immune system tends to reject foreign objects?
To learn the answer of the above question first we have to know about the blood characteristics.There are four major types of blood A, B, AB, and 0. The blood types are determined by proteins called antigens. This antigen is found on the surface of the Red Blood Cell (RBC). Basically there are two antigens, A and B. If you have the A antigen on the RBC, then you have type A blood. When B antigen is present, you have type B blood. When both A and B antigens are present, you have type AB blood. When either are present, you have type O blood. When an antigen is resent on the RBC, then the opposite antibody is present in the plasma. For instance, type A blood has anti-type-B antibodies. Type B blood has anti-type-A antibodies. Type AB blood has no antibodies in the plasma, and type O blood has both anti-type-A and anti-type-B antibodies in the plasma. These antibodies are not present at birth but are formed spontaneously during infancy and last throughout life. In addition to the ABO blood group system, there is an Rh blood group system. There are many Rh antigens that can be present on the surface of the RBC. The D antigen is the most common Rh antigen. If the D antigen is present, then that blood is Rh+. If the D antigen is missing, then the blood is Rh-. Blood is transfused to a patient after determining the blood group and matching the characteristics of both. In such case the immune system accepts the foreign object.
What is the exact nature of antibodies?
antibodies are immune cells which are present in the immune system and it helps in , if any foregin particles or antigens enters in our body it kills that antigen or it binds to the antigen and forms the antigen _antibody complex
