Role Of Myeloid Cell-Specific Adenylyl Cyclase Type 7 In Lipopolysaccharide- And Alcohol-Induced Immune Responses, Yawen Hu, Sonika Patial, Yogesh Saini, Masami Yoshimura

School of Graduate Studies Faculty Publications

Clinical and experimental evidence indicates that alcohol use causes various abnormalities in the immune system and compromises immune functions. However, the mechanistic understanding of ethanol’s effects on the immune system remains limited. Cyclic AMP (cAMP) regulates multiple processes, including immune responses. Earlier research indicated that type 7 adenylyl cyclase (AC7) regulates the immune system and is highly responsive to ethanol. Therefore, we hypothesized that AC7 is a central player in regulating the effects of alcohol on innate immune responses. To test this hypothesis, we utilized a myeloid lineage-specific AC7 KO mouse model and compared the effects of acute and chronic …

Addressing drug-induced liver injury is crucial in drug development, often causing Phase III trial failures and market withdrawals. Traditional animal models fail to predict human liver toxicity accurately. Virtual twins of human organs present a promising solution. We introduce the Virtual Hepatic Lobule, a foundational element of the Living Liver, a multi-scale liver virtual twin. This model integrates blood flow dynamics and an acetaminophen-induced injury model to predict hepatocyte injury patterns specific to patients. By incorporating metabolic zonation, our predictions align with clinical zonal hepatotoxicity observations. This methodology advances the development of a human liver virtual twin, aiding in the …

Most respiratory microbiome studies use amplicon sequencing due to high host DNA. Metagenomics sequencing offers finer taxonomic resolution, phage assessment, and functional characterization. We evaluated five host DNA depletion methods on frozen nasal swabs from healthy adults, sputum from people with cystic fibrosis (pwCF), and bronchoalveolar lavage (BAL) from critically ill patients. Median sequencing depth was 76.4 million reads per sample. Untreated nasal, sputum, and BAL had 94.1%, 99.2%, and 99.7% host reads, respectively. Host depletion effects varied by sample type, generally increasing microbial reads, species and functional richness; this was mediated by higher effective sequencing depth. Rarefaction curves showed …

Human Single Cell Rna-Sequencing Reveals A Targetable Cd8+ Exhausted T Cell Population That Maintains Mouse Low-Grade Glioma Growth, Rasha Barakat, Jit Chatterjee, Rui Mu, Xuanhe Qi, Xingxing Gu, Igor Smirnov, Olivia Cobb, Karen Gao, Angelica Barnes, Jonathan Kipnis, David H Gutmann

2020-Current year OA Pubs

In solid cancers, T cells typically function as cytotoxic effectors to limit tumor growth, prompting therapies that capitalize upon this antineoplastic property (immune checkpoint inhibition; ICI). Unfortunately, ICI treatments have been largely ineffective for high-grade brain tumors (gliomas; HGGs). Leveraging several single-cell RNA sequencing datasets, we report greater CD8
