Background
Phenotypic characterization of immune cells in the bone marrow (BM) of patients with acute myeloid leukemia (AML) is lacking.
Methods
T‐cell infiltration was quantified on BM biopsies from 13 patients with AML, and flow cytometry was performed on BM aspirates (BMAs) from 107 patients with AML who received treatment at The University of Texas MD Anderson Cancer Center. The authors evaluated...
Tumor microenvironment contributes to a large extent for failure of immunological destruction of antigenic tumors. Most solid tumors adapt to the microenvironment and escape the host immune system. The dramatic and systemic effectiveness of neuro-immune ligand Capsaicin (CP) in regression of established solid tumors led us to investigate its immunomodulatory role in tumor microenvironment. In this...
Vanilloid receptor1 (VR1/TRPV1) is expressed on peripheral nerves and involved in sensing of temperature and pain. Recent reports have demonstrated that tumor cells express TRPV1 and that capsaicin (CP), a ligand for TRPV1, induces apoptosis in cancer cells. The mechanism underlying CP-induced tumor cell apoptosis remains unclear. Here, we investigated the role of TRPV1 in tumor apoptosis using TRPV1-expressing...
The heat shock protein-antigen presenting cell interaction lies at the center of the unique properties of heat shock proteins as immunogens. This interaction is a key event in adaptive immune response elicited by heat shock protein-chaperoned peptides, naturally derived or artificially reconstituted. The heat shock protein-antigen presenting cell interaction results in a primitive and fundamental...
Complexes of the heat shock protein gp96 and antigenic peptides are taken up by antigen-presenting cells and presented by MHC class I molecules. In order to explain the unusual efficiency of this process, the uptake of gp96 had been postulated to occur through a receptor, identified recently as CD91. We show here that complexes of peptides with heat shock proteins hsp90, calreticulin, and hsp70 are...
