The Dobos laboratory is focused on descriptive, comparative studies of Mycobacterium tuberculosis strains that are relevant to the development of second-generation vaccines and diagnostic assays. Specifically, the laboratory utilizes mass spectrometry, animal models of tuberculosis, and collaborations with clinical research groups to define macromolecules engaged in host-parasite interactions. This is accomplished through highly collaborative studies within CSU (principally with the laboratories of Drs. Angelo Izzo and Nicole Kruh-Garcia) and outside of the University.
Microbiology and Infectious Diseases Biological Research Repository (MID-BRR)
The Dobos laboratory provides crude and purified reagents from M. tuberculosis, M. leprae, and other specialized Mycobacterium species and transfers these reagents to the MID-BRR repository managed by American Type Culture Collection. Products include irradiated cells, subcellular fractions, genomic DNA, crude lipids, purified lipids, lipoglycans, native proteins, and antibodies/antisera.view project
Collaborations with Oregon Health and Sciences University
The Lewinsohn lab focuses on understanding how human CD8+ T cells recognize cell infected with Mycobacterium tuberculosis (Mtb). Areas of interest include defining the repertoire of immunodominant antigens in Mtb, defining the mechanisms by which Mtb-antigens can enter the HLA-I antigen processing pathway, and defining the mechanisms by which innate T cells can recognize cells infected with Mtb.view project
Collaborations with Saint Louis University
Dr. Daniel Hoft treats patients for infectious diseases. His areas of expertise include tuberculosis, parasitology, and vaccination. He is particularly interested in research into vaccine development, especially for Chagas disease, pandemic influenza, and tuberculosis.view project
CDC PHEPRAR contract
The Dobos lab will establish conditions for kill curves for requested genus. After surrogate kill curves are established, ATCC will provide “select agent” genus/species to be tested. These will be irradiated at one dose higher than the minimum dose required to kill the surrogate. The Dobos laboratory provides scientific expertise on the irradiation of select agents and surrogates/near neighbors.
