IL-15-secreting CAR natural killer cells directed toward the pan-cancer target CD70 eliminate both cancer cells and cancer-associated fibroblasts.

Background: It remains challenging to obtain positive outcomes with chimeric antigen receptor (CAR)-engineered cell therapies in solid malignancies, like colorectal cancer (CRC) and pancreatic ductal adenocarcinoma (PDAC). A major obstacle is the lack of targetable surface antigens that are not shared by healthy tissues. CD70 emerges as interesting target, due to its stringent expression pattern in healthy tissue and its apparent role in tumor progression in a considerable amount of malignancies.

Small Airway Disease in Pre-Chronic Obstructive Pulmonary Disease with Emphysema: A Cross-Sectional Study.

Small airway disease is an important pathophysiological feature of chronic obstructive pulmonary disease (COPD). Recently, "pre-COPD" has been put forward as a potential precursor stage of COPD that is defined by abnormal spirometry findings or significant emphysema on computed tomography (CT) in the absence of airflow obstruction. To determine the degree and nature of (small) airway disease in pre-COPD using microCT in a cohort of explant lobes/lungs.

Upper-extremity spasticity and functionality after selective dorsal rhizotomy for cerebral palsy: a systematic review.

Objective: Lumbosacral selective dorsal rhizotomy is a neurosurgical treatment option to reduce spasticity in the lower extremities in children with cerebral palsy. Surprisingly, concomitant improvement of spasticity in the upper extremities and functionality of the hands has been sporadically reported postoperatively. In this systematic review, the authors aimed to quantify the postoperative improvement in upper-extremity spasticity and functionality, identify predictors, and discuss underlying mechanisms.

PD-1, PD-L1, IDO, CD70 and microsatellite instability as potential targets to prevent immune evasion in sarcomas.

Soft tissue and bone sarcomas are rare entities, hence, standardized therapeutic strategies are difficult to assess. Immunohistochemistry was performed on 68 sarcoma samples to assess the expression of PD-1, PD-L1, IDO and CD70 in different tumor compartments and molecular analysis was performed to assess microsatellite instability status. PD-1/PD-L1, IDO and CD70 pathways are at play in the immune evasion of sarcomas in general.
