A randomized clinical trial of BM vs. blood stem cell transplants from unrelated donors showed that more plasmacytoid dendritic cells (pDCs) in BM grafts was associated with better post-transplant survival. Here, we describe differences in homing-receptor expression on pDC to explain observed differences following BM vs. blood stem cell transplantation.

Uncommon epidermal growth factor receptor (EGFR) mutations in non-small cell lung cancer (NSCLC) pose therapeutic challenge due to limited response to EGFR tyrosine kinase inhibitors (TKIs). This study presents preclinical evidence and mechanistic insights into the combination of lazertinib, a third-generation EGFR-TKI; and amivantamab, an EGFR-MET bispecific antibody, for treating NSCLC with uncommon EGFR mutations. The lazertinib-amivantamab combination demonstrates significant antitumor activity in patient-derived models with uncommon EGFR mutations either before treatment or after progressing on EGFR-TKIs.

Clear cell renal cell carcinoma is a prevalent urological malignancy, imposing substantial burdens on both patients and society. In our study, we used bioinformatics methods to select four putative target genes associated with EMT and prognosis and developed a nomogram model which could accurately predicting 5-year patient survival rates. We further analyzed proteome and single-cell data and selected PLCG2 and TMEM38A for the following experiments.

Background: Neuroinflammation plays a major role in amyotrophic lateral sclerosis (ALS), and cumulative evidence suggests that systemic inflammation and the infiltration of immune cells into the brain contribute to this process. However, no study has investigated the role of peripheral blood immune cells in ALS pathophysiology using single-cell RNA sequencing (scRNAseq).
Methods: We aimed to characterize immune cells from blood and identify ALS-related immune alterations at single-cell resolution.

Dendritic cell (DC) activation by pattern recognition receptors like Toll-like-receptors (TLRs) is crucial for cancer immunotherapies. Here, we demonstrate the effectiveness of the TLR7/8 agonist imiquimod (IMQ) in treating both local tumors and distant metastases. Administered orally, IMQ activates plasmacytoid DCs (pDCs) to produce systemic type I interferons (IFN-I) required for TLR7/8 upregulation in DCs and macrophages, sensitizing them to topical IMQ treatment, which is essential for therapeutic efficacy.

A series of isatin derivatives which could inhibit colorectal cancer (CRC) were synthesized. Among those compounds, 5B exhibited good inhibitory activity of CRC through the inhibition of tubulin expression, inducing apoptosis, and causing G2/M phase cell cycle arrest pathway, which suggested that 5B could be a potential tubulin inhibitor. Based on that, a novel peptide-drug conjugate (PDC), which employed the CRC cells related receptor CD44 ligand peptide A6 coupling to 5B to accomplish A6-5B.
