IgG and IgM antibody levels to mycobacterial lipoarabinomannan (LAM) antigen were determined by ELISA in eight sooty mangabey monkeys (Cercocebus atys) prior to and at intervals after experimental inoculation with Mycobacterium leprae. (unboundmedicine.com)
Anti-LAM antibody levels appear to be potentially valuable as an indicator of leprosy susceptibility, and when measured longitudinally together with antibody levels to M. leprae-specific phenolic glycolipid-I antigen, as a means to detect preclinical M. leprae infections in high-risk individuals.

We now evaluate whether we can enhance wild-type (WT) or p50-IMC tumor localization and/or the phagocytosis of PSMA+ prostate cancer cells by expressing a prostate-specific membrane antigen (PSMA)-specific chimeric antigen receptor (CAR) on IMC, or by combining IMC with PSMA antibody (Ab), which binds to the surface of myeloid cells via their Fc receptors. (bmj.com)
In response to this trigger, the body starts making a type of protein called IgE or immunoglobulin E. IgE molecules bind with the allergen molecules in an antigen-antibody reaction. (onteenstoday.com)
IgE molecules bind with the allergen molecules in an antigen-antibody reaction. (onteenstoday.com)
This attachment of the antigen and antibody leads to the release of some chemicals (such as histamine) in the body. (onteenstoday.com)
Together, these modifications provide a specific set of instructions to the innate immune system to direct the elimination of antibody-bound antigens. (harvard.edu)
Here, we show that antibody glycosylation is determined in an antigen- and pathogen-specific manner during HIV infection. (harvard.edu)
Moreover, while dramatic differences exist in bulk IgG glycosylation among individuals in distinct geographical locations, immunization is able to overcome these differences and elicit antigen-specific antibodies with similar antibody glycosylation patterns. (harvard.edu)
Additionally, distinct vaccine regimens induced different antigen-specific IgG glycosylation profiles, suggesting that antibody glycosylation is not only programmable but can be manipulated via the delivery of distinct inflammatory signals during B cell priming. (harvard.edu)
These data strongly suggest that the immune system naturally drives antibody glycosylation in an antigen-specific manner and highlights a promising means by which next-generation therapeutics and vaccines can harness the antiviral activity of the innate immune system via directed alterations in antibody glycosylation in vivo.

(cdc.gov)
In the United States, the implementation of antibody testing in 1985 of all donated blood for human immunodeficiency virus type 1 (HIV-1) resulted in a substantial decrease in the transmission of HIV through blood transfusions (1,2). (cdc.gov)
