A case of pulmonary hyalinizing granuloma (PHG) and concomitant low-grade, small lymphocytic lymphoma of the lung is presented. This is the first occurrence of pulmonary lymphoma in patients with PHG ever reported. The infiltrates around a left lower lobe nodule with left pleural effusion and thickening seen on chest CT were histologically proven to be lymphomatous infiltrates of the lung, pleura, and chest wall muscle. We believe that the lymphoma developed around the nodule and spread to the pleura and muscle in our patient. When infiltrates around the nodules, pleural effusion, or adenopathy are developed in a patient with proven PHG, close follow-up, biopsy, or careful cytology should be seriously considered to rule out a developing lymphoma.

Oncolytic reprogramming of tumor microenvironment shapes CD4 T-cell memory via the IL6ra-Bcl6 axis for targeted control of glioblastoma.

Oncolytic viruses (OVs) emerge as a promising cancer immunotherapy. However, the temporal impact on tumor cells and the tumor microenvironment, and the nature of anti-tumor immunity post-therapy remain largely unclear. Here we report that CD4 T cells are required for durable tumor control in syngeneic murine models of glioblastoma multiforme after treatment with an oncolytic herpes simplex virus (oHSV) engineered to express IL-12.

Animal thermoregulation may have significant costs and compete directly or indirectly with other energetically demanding processes, such as immune function. Although the subterranean environment is characterized by thermally-stable conditions, small changes in ambient temperature could be critical in shaping immunity. However, little is known about the effects of ambient temperature, in naturally varying ranges, on immunity of wild species.

Purpose Of The Review: Calcineurin inhibitors (CNIs) are central to immunosuppression in kidney transplantation (KT), improving short-term outcomes but falling short in enhancing long-term outcomes due to cardiovascular, metabolic, and renal complications. Belatacept, an FDA-approved costimulation blocker, offers a less toxic alternative to CNIs but is limited by its intravenous administration and reduced efficacy in high-immunological-risk patients.
Recent Findings: Emerging therapies target more specific pathways to improve efficacy and accessibility.

Immune checkpoint blockade (ICB) combined with radiotherapy (RT) has improved patients survival, but also increased the risk of pulmonary adverse effects (AEs). Therefore, to explore potential drug targets for interstitial lung disease (ILD), we investigated the interaction of ICB and RT in pulmonary AEs using the disproportionality analysis and COX regression. Genome-wide association studies, transcriptome analysis, and vivo models highlighted the role of programmed death-ligand-1 (PD-L1) in ILD.

Background: Different doses of radiotherapy (RT) exert diverse effects on tumor immunity, although the precise irradiation method remains unknown. This study sought to elucidate the influence of combining different doses of RT with immune checkpoint inhibitors (ICIs) on the infiltration of CD8T cells within tumors, thereby augmenting the anti-tumor response.
Methods: Constructing a mouse model featuring bilateral lung cancer tumors subjected to high and low dose irradiation, the analysis of RNA transcriptome sequencing data and immunohistochemical validation for tumors exposed to various dosages guided the selection of the optimal low-dose irradiation scheme.
