Attana
New publication from National University of Singapore using Attana Technology to study Immune Response from Tuberculosis Exposed Healthy Individuals
The group at NUS has published several papers using Attana technology to identify correlation between protective immune response of human immune antibodies. Work has been published for e.g. Hepatitis B, Covid-19 and, now Tuberculosis. Whereas the two first diseases are virus born, TB is a bacterial disease. For Attana, the paper is important since it forms yet another example of the generic applicability of Attana technology in immune response research. It also demonstrates that more information than pure affinity is necessary to identify the best protecting antibodies. A crucial factor to secure a good protection is by the kinetics of the on-rate, where an on-rate for IgG antibodies equal to, or faster than 106Mol/s provides a good protection. Secondly the IgA antibodies, which are dimeric antibodies, probably have an initial function to inhibit the adhesion of bacteria, and hence slows down the infection process.
In the picture kinetic interaction results of immune antibodies are shown. Demonstrating larger variations in kinetics compared to traditional affinity, hence important information for understanding protection and optimizing vaccine candidates or for selecting optimal antibodies for therapeutics.
