A adenosine receptor antagonists rescue lymphocyte activity in adenosine-producing patient-derived cancer models.

J Immunother Cancer 2022 May;10(5)

Department of Oncology-Pathology, Karolinska Institute, Stockholm, Sweden

Background: Adenosine is a metabolite that suppresses antitumor immune response of T and NK cells via extracellular binding to the two subtypes of adenosine-2 receptors, AARs. While blockade of the AARs subtype effectively rescues lymphocyte activity, with four AAR antagonists currently in anticancer clinical trials, less is known for the therapeutic potential of the other AAR blockade within cancer immunotherapy. Recent studies suggest the formation of AAR/AAR dimers in tissues that coexpress the two receptor subtypes, where the AAR plays a dominant role, suggesting it as a promising target for cancer immunotherapy.

Soluble HLA peptidome of pleural effusions is a valuable source for tumor antigens.

J Immunother Cancer 2022 May;10(5)

Institute of Pulmonary Medicine, Chaim Sheba Medical Center, Ramat Gan, Israel

Background: Soluble human leucocyte antigen (sHLA) molecules, released into the plasma, carry their original peptide cargo and provide insight into the protein synthesis and degradation schemes of their source cells and tissues. Other body fluids, such as pleural effusions, may also contain sHLA-peptide complexes, and can potentially serve as a source of tumor antigens since these fluids are drained from the tumor microenvironment. We explored this possibility by developing a methodology for purifying and analyzing large pleural effusion sHLA class I peptidomes of patients with malignancies or benign diseases. Read More
