Dual activation of the TLR7 and TLR8 pathways leads to the production of type I interferon and proinflammatory cytokines, resulting in efficient antigen presentation by dendritic cells to promote T-cell priming and antitumor immunity. We developed a novel series of TLR7/8 dual agonists with varying ratios of TLR7 and TLR8 activity for use as payloads for an antibody-drug conjugate approach. The agonist-induced production of several cytokines in human whole blood confirmed their functional activity.

In this paper, we introduce a novel concordance-based predictive uncertainty (CPU)-Index, which integrates insights from subgroup analysis and personalized AI time-to-event models. Through its application in refining lung cancer screening (LCS) predictions generated by an individualized AI time-to-event model trained with fused data of low dose CT (LDCT) radiomics with patient demographics, we demonstrate its effectiveness, resulting in improved risk assessment compared to the Lung CT Screening Reporting & Data System (Lung-RADS). Subgroup-based Lung-RADS faces challenges in representing individual variations and relies on a limited set of predefined characteristics, resulting in variable predictions.

Across cell types and organisms, thousands of RNAs display asymmetric subcellular distributions. The study of this process often requires quantifying abundances of specific RNAs at precise subcellular locations. To analyze subcellular transcriptomes, multiple proximity-based techniques have been developed in which RNAs near a localized bait protein are specifically labeled, facilitating their biotinylation and purification.
