1.GSE285325 单细胞 RNA 测序分析揭示了淋巴液图谱并发现了一种与脓毒症相关的 T 细胞亚群

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:lymph、T cell、regex:lymph(o|atic)?、RNA-seq、single-cell
  • 📝 描述:Contributors : Hui Wang ; Jianguang WangSeries Type : Expression profiling by high throughput sequencingOrganism : Rattus norvegicusThe lymphoid cycle as the sentinel of immune response, its cell subtypes and immune properties and functions during sepsis are still unclear. This study described a comprehensive picture of immune cells in rat lymph fluid by single-cell RNA sequencing and identified a unique subset of CD4+ T cells (CD4_Icos) in the early state of sepsis, confirming its crucial role in Treg cell production. Transferring with CD4+Icos+ T cells significantly alleviated CLP-induced organ injury, while Icosfl/flCd4-CreERT2 mice showed reduced number of Treg and increased inflammation and mortality risk. Further screening and validation experiments identified Npas2 as an Icos-specific transcription factor that regulates Icos expression and promotes the differentiation of CD4+Icos+ T cells. Clinical results disclosed the negative correlation between the expression of ICOS in CD4+ T cells and SOFA score in septic patients, which affected the prognosis of septic patients. These findings indicated the protective role of CD4+ T cells in sepsis.

  • 🏷️ 关键词:tumor、cancer、inflammation、scRNA
  • 📝 描述:Contributors : Neil Carleton ; Alexander Chang ; Steffi Oesterreich ; Adrian LeeSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensEstrogen receptor positive (ER+) breast cancer, the most common subtype of breast cancer, is an age-related disease, with the peak incidence of diagnosis occurring around age 70 despite low circulating levels of estradiol. Despite the hormone sensitivity of these age-related tumors, our understanding of the interplay between the systemic and local hormonal disposition and chronic inflammaging is limited. We show that aged F344 rats treated with the DMBA/MPA carcinogen develop more tumors at faster rates than their younger counterparts, suggesting that the aged environment accelerates tumor growth. snRNA-seq of the tumors showed broad local immune dysfunction that was associated with circulating chronic inflammation. Across a broad cohort of specimens from patients with ER+ breast cancer and age-matched donors of normal breast tissue, we observe that even with E1-predominant estrogen disposition in the systemic circulation, tumors in older patients upregulate HSD17B7 expression to convert E1 to E2 in the TME. Age-related accumulation of tumor-associated macrophages serve as signaling hubs that integrate the E2 and chemokine-driven chronic inflammatory signaling in the TME, which polarize TAMs towards a CD206+/PD-L1+, immunosuppressive phenotype. Overall, these findings suggest that the host’s chronic inflammation and hormonal disposition shape the local tumor microenvironment and are critical contributors to the age-related nature of ER+ breast cancer development and growth.

10.GSE333980 果蝇硫代谢基因敲除诱导慢性炎症和免疫失调

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:immune、inflammation、metabolism
  • 📝 描述:Contributors : O.G Zatsepina ; V.A Shilova ; M.B. Evgen’ev ; A.P Rezvykh ; D.G GarbuzSeries Type : Expression profiling by high throughput sequencingOrganism : Drosophila melanogasterIn this study, we examined a unique collection of Drosophila melanogaster strains with knockouts of three key genes involved in H₂S synthesis and metabolism, with the aim of elucidating the role of this adaptive system in immunity. Genetic disruptions in sulfur metabolism—specifically, combined deletions of the cbs, cse, and tst1 genes—lead to reduced H₂S levels and hyperhomocysteinemia in flies. These metabolic changes induce oxidative stress and trigger chronic inflammatory responses. Transcriptomic analysis and q-PCR revealed significant activation of major immune pathways, including IMD, Toll, and Jac-Stat. A septic injection of Bacillus subtilis induces increased expression of antimicrobial peptides (AMPs) and pattern recognition receptors in knockout flies. Notably, double- and triple-knockout strains exhibit prolonged immune activation. The triple knockout exhibits the worst survival rate following septic injury induced by Bacillus subtilis. These results highlight the critical role of H₂S in modulating innate immunity and suggest that sulfur metabolism is an important regulator of inflammatory homeostasis in Drosophila.
