Introduction of altered antigens involves exposing the immune system to modified versions of antigens to trigger an immune response without causing disease. This approach can be used in vaccine development to stimulate immune memory and protection against specific pathogens or diseases. Altered antigens can include weakened or inactivated forms of pathogens, as well as genetically engineered antigens.

The earliest sign of increased intracranial pressure is often a headache that is worse in the morning, and improves throughout the day when in an upright position. Other early signs can include nausea and vomiting, changes in vision, and altered mental status.

Most persons who experience significant symptoms have an altered immune system, and suffer from diseases such as AIDS and cancer.
Antigens, which trigger the immune response in the body, originate from foreign substances like bacteria, viruses, and other pathogens, as well as from the body's own cells that have been altered or damaged.
In one approach, genes that produce specific HIV proteins have been altered to stimulate immune system functioning without causing the negative effects that a complete HIV molecule has on the immune system
An allergist/immunologist specializes in diagnosing and treating conditions of altered immunologic reactivity such as allergies, asthma, and autoimmune diseases. They are trained to identify and manage conditions related to the immune system's response to various triggers.
The BCG vaccine contains a strain of mycobacterium bovis, which is a bacterium that causes tuberculosis (TB) in cattle. The bacteria have been altered so that they do not cause a TB infection but make your immune system produce antibodies. These make you immune (resistant) to the disease.
No, antibodies are not proteins that catalyze chemical reactions without being physically altered. Antibodies are proteins produced by the immune system to help recognize and neutralize foreign substances, such as bacteria and viruses. Enzymes are proteins that catalyze chemical reactions without being physically altered.
Dead or altered viruses or bacteria that are used to stimulate the body's immune response are called vaccines. Vaccines contain weakened or inactivated forms of the pathogen, or certain proteins or subunits of the pathogen, to trigger an immune response without causing the disease. This allows the body to recognize and fight the pathogen more effectively if encountered in the future.
