An Activin Receptor-Like Kinase 1-governed monocytic lineage shapes an immunosuppressive landscape in breast cancer metastases.

The biology centered around the TGF-beta type I receptor Activin Receptor-Like Kinase (ALK)1 (encoded by ACVRL1) has been almost exclusively based on its reported endothelial expression pattern since its first functional characterization more than two decades ago. Here, in efforts to better define the therapeutic context in which to use ALK1 inhibitors, we uncover a population of tumor-associated macrophages (TAMs) that, by virtue of their unanticipated Acvrl1 expression, are effector targets for adjuvant anti-angiogenic immunotherapy in mouse models of metastatic breast cancer. The combinatorial benefit depended on ALK1-mediated modulation of the differentiation potential of bone marrow-derived granulocyte-macrophage progenitors, the release of CD14+ monocytes into circulation, and their eventual extravasation.

Background: Cervical cancer disparities persist among minoritized women due to infrequent screening and poor follow-up. Structural and psychosocial barriers to following up with colposcopy are problematic for minoritized women. Evidence-based interventions using patient navigation and tailored telephone counseling, including the Tailored Communication for Cervical Cancer Risk (TC3), have modestly improved colposcopy attendance.

For the first time, a separate Czech guideline focuses exclusively on hepatitis D virus (HDV) infection. Until recently, HDV infection was only mentioned in guidelines concerning hepatitis B virus (HBV) infection, in chapters on HBV/HDV co-infection. The guideline is based on the July 2023 recommendations from the European Association for the Study of the Liver.

Based on the notion that hypomorphic germline genetic variants are linked to autoimmune diseases, we reasoned that novel targets for cancer immunotherapy might be identified through germline variants associated with greater T-cell infiltration into tumors. Here, we report that while investigating germline polymorphisms associated with a tumor immune gene signature, we identified PKCδ as a candidate. Genetic deletion of PKCδ in mice resulted in improved endogenous antitumor immunity and increased efficacy of anti-PD-L1.
