Lewinsohn Laboratory: CD8 T Cell Recognition of Intracellular Infection with Mtb
The Lewinsohn laboratory is
focused on understanding the mechanisms by which human CD8+ T cells recognize
cell infected with Mycobacterium tuberculosis (Mtb), the bacteria responsible
for tuberculosis. Areas of interest within the laboratory include:
the repertoire of immunodominant antigens in Mtb. Here, we have focused on antigens that are
presented by classical HLA molecules (HLA-A, B, and C) as well as those
presented by non-classical molecules such has HLA-E.
2) Defining the mechanisms
by which Mtb-antigens can enter the HLA-I antigen processing pathway. Because Mtb is an organisms normally found
within the phagosome (traditionally a HLA-II processing compartment). We are
currently focused on the role of the phagosome as a HLA-I processing
3) Defining the mechanisms by which innate T cells can recognize those cells infected with Mtb. Here, early recognition of these cells might directly limit intracellular replication of Mtb, or might promote the development of an effective adaptive immune response.
