Dr. Abraham Pinter has been part of an ongoing study led by The Foundation for Innovative New Diagnostics (FIND) to develop a fast diagnotic test to detect tuberculosis in people infected with HIV. For details, visit www.rutgers.edu.

With the inability of available HIV-1 vaccines to achieve protection, there is a clear need for the identification of novel vaccine targets and approaches. A key focus of the work of Dr. Pinter’s lab is understanding the basis for the inability of the immune system to control HIV, and identification of new targets and vaccine approaches that may be able to overcome these limitations. The role of conformational masking towards neutralization resistance is being analyzed in detail, with a focus on specific determinants that contribute to masking and identification of mutations that can reverse this effect.

A second line of research in the Pinter lab is exploiting the human humoral response to identify novel antibodies and epitopes that may have clinical utility. In addition to the focus on HIV, these studies have recently been extended towards mycobacterial pathogens, including M.tb, the infectious agent for tuberculosis.  This has led to the isolation and characterization of novel monoclonal antibodies (mAbs) from infected patients with high affinities towards the major surface glycolipid of M.tb, lipoarabinomannan (LAM). These antibodies have allowed the development of a sensitive assay that can detect the presence of LAM in the urine of most patients actively infected with TB. Current studies are directed at improving the sensitivity of these reagents so that they can be developed as an effective point-of-care assay for TB infection, and to study the potential of human mAbs against LAM and other protein and glycoprotein TB antigens to control M.tb. infection and pathogenicity.
