Junctional adhesion molecule-A (JAM-A), expressed on the surface of myeloid cells, is required for extravasation at sites of inflammation and may also modulate myeloid cell activation. Infiltration of myeloid cells is a common feature of tumors that drives disease progression, but the function of JAM-A in this phenomenon and its impact on tumor-infiltrating myeloid cells is little understood. Here we show that systemic cancer-associated inflammation in mice enhanced JAM-A expression selectively on circulating monocytes in an IL1β-dependent manner.

Understanding the cancer cell-intrinsic and microenvironmental determinants of αCD40 therapy response is therefore crucial to identify responsive patient populations and to design efficient combinatorial treatments. Here, we show that the therapeutic efficacy of αCD40 in subcutaneous melanoma relies on preexisting, type 1 classical dendritic cell (cDC1)-primed CD8+ T cells.

- The combination of radiotherapy (RT) and immunotherapy shows potential for improving treatment outcomes in non-small cell lung cancer (NSCLC) patients, but current response rates are low and require further optimization.
- In preclinical studies using mice, vagal nerve stimulation (VNS) was tested alone and with RT, revealing that while it didn't significantly impact tumor growth, VNS enhanced the activation of CD8 T cells and altered immune profiles in the tumor environment.
- Clinical trials involving NSCLC patients indicated that VNS alone did not lead to significant immune changes in the blood, but the findings suggest ongoing research into VNS could help improve response rates to combined RT and immunotherapy treatments.
Cement is the most produced material in the world. A major player in greenhouse gas emissions, it is the main binding agent in concrete, providing a cohesive strength that rapidly increases during setting. Understanding how such cohesion emerges is a major obstacle to advances in cement science and technology.

Methods: We employed single-cell RNA-sequencing in a mouse model of non-small cell lung carcinoma (NSCLC) to obtain a comprehensive overview of the tumor-infiltrating T-cell compartment, with a focus on ti-Treg subpopulations. These findings were validated by flow cytometric analysis of both mouse (LLC-OVA, MC38 and B16-OVA) and human (NSCLC and melanoma) tumor samples.
