AI Article Synopsis

  • Researchers are focusing on creating new immune boosters that trigger cellular immune responses by using two specific immune receptors, NOD2 and TLR7, together.
  • The study explores how different chemical linkers impact the effectiveness and solubility of these immune-activating compounds, showing they can significantly enhance immune responses in human immune cells.
  • Findings suggest that the design of these compounds can be optimized for better immune activation, contributing valuable knowledge for future immune booster development.

Article Abstract

There is a growing interest in developing novel immune potentiators capable of eliciting a cellular immune response. We tackle this challenge by harnessing the synergistic cross-activation between two innate immune receptors─the nucleotide-binding oligomerization domain-containing protein 2 (NOD2) and Toll-like receptor 7 (TLR7). Herein, we investigate the structure-activity relationship of a series of novel conjugated NOD2/TLR7 agonists incorporating a variety of flexible aliphatic, poly(ethylene glycol)-based and triazole-featuring linkers. Our findings reveal potent immune-enhancing properties of conjugates in human primary peripheral blood mononuclear cells, characterized by a Th1/Th17 polarized cytokine response. Importantly, we demonstrate that both the chemistry of the linker and the site of linkage affect the immune fingerprint and the kinetic solubility of these conjugated agonists. These results shed further light on the immunostimulatory potential of NOD2/TLR7 cross-activation and provide insights for designing innovative immune potentiators.

Purpose: Immune checkpoint inhibitors (ICIs) are now first-line therapy for most patients with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC), and cetuximab is most often used as subsequent therapy. However, data describing cetuximab efficacy in the post-ICI setting are limited.

Methods: We performed a single-institution retrospective analysis of patients with R/M HNSCC treated with cetuximab, either as monotherapy or in combination with chemotherapy, after receiving an ICI.

Most diffuse large B-cell lymphoma (DLBCL) patients treated with immunotherapies such as bispecific antibodies (BsAb) or chimeric antigen receptor (CAR) T cells fail to achieve durable treatment responses, underscoring the need for a deeper understanding of mechanisms that regulate the immune environment and response to treatment. Here, an integrative, multi-omic approach was applied to multiple large independent datasets in order to characterize DLBCL immune environments, and to define their association with tumor cell-intrinsic genomic alterations and outcomes to CD19-directed CAR T-cell and CD20 x CD3 BsAb therapies. This approach effectively segregated DLBCLs into four immune quadrants (IQ) defined by cell-of-origin and immune-related gene set expression scores.

The mosquito midgut functions as a key interface between pathogen and vector. However, studies of midgut physiology and virus infection dynamics are scarce, and in Culex tarsalis-an extremely efficient vector of West Nile virus (WNV)-nonexistent. We performed single-cell RNA sequencing on Cx.

Background: Antiretroviral therapy (ART) restores cellular immunity, significantly reducing AIDS-related mortality and morbidity thus improving the quality of life among People living with HIV (PLHIV). Studies done in several countries show a decline in AIDS defining cancers (ADCs) with the introduction of ART however the increased longevity has led to the increase of Non-AIDS defining cancers (NADCs). The study was aimed at studying the changing spectrum and trends of cancer among Human Immunodeficiency Virus (HIV) patients in southwestern Uganda.

Suppressing Tymovirus replication in plants using a variant of ubiquitin.

PLoS Pathog

RNA viruses have evolved numerous strategies to overcome host resistance and immunity, including the use of multifunctional proteases that not only cleave viral polyproteins during virus replication but also deubiquitinate cellular proteins to suppress ubiquitin (Ub)-mediated antiviral mechanisms. Here, we report an approach to attenuate the infection of Arabidopsis thaliana by Turnip Yellow Mosaic Virus (TYMV) by suppressing the polyprotein cleavage and deubiquitination activities of the TYMV protease (PRO). Performing selections using a library of phage-displayed Ub variants (UbVs) for binding to recombinant PRO yielded several UbVs that bound the viral protease with nanomolar affinities and blocked its function.
