AI Article Synopsis

  • Human cytomegalovirus (CMV) significantly affects individuals with weakened immune systems, yet no effective vaccine exists.
  • Identifying target proteins and T-cell epitopes is essential for creating a successful vaccine and for new techniques involving T-cell therapy.
  • The study introduces a streamlined SPOT synthesis method to create and test all potential CD8 T-cell epitopes from the CMV proteome, leading to the discovery of many known and novel epitopes after testing over 9,000 peptides.

Article Abstract

Human cytomegalovirus (CMV) is a major cause of morbidity in immunocompromised individuals. However, no efficient vaccine has been developed to date. Identification of T-cell target proteins and epitopes is crucial not only for developing a successful immunization strategy, but also for new approaches using adoptive transfer of antigen-specific T-cells. The CMV genome has more than 200 open reading frames potentially coding for as many proteins. Here, we describe a robust, fast, and simple SPOT synthesis strategy, which allowed us to micro-synthesize every possible CD8 T-cell epitope in the entire potential CMV proteome. So far, 9069 of these peptides have been tested in an ex vivo T-cell stimulation assay. As well as confirming a number of previously known epitopes, we identified several new ones.

Background: The antigen Na-GST-1, expressed by the hookworm Necator americanus, plays crucial biochemical roles in parasite survival. This study explores the development of mRNA vaccine candidates based on Na-GST-1, building on the success of recombinant Na-GST-1 (rNa-GST-1) protein, currently assessed as a subunit vaccine candidate, which has shown promise in preclinical and clinical studies.

Methodology/findings: By leveraging the flexible design of RNA vaccines and protein intracellular trafficking signal sequences, we developed three variants of Na-GST-1 as native (cytosolic), secretory, and plasma membrane-anchored (PM) antigens.

Noncanonical UPR factor CREB3L2 drives immune evasion of triple-negative breast cancer through Hedgehog pathway modulation in T cells.

The unfolded protein response (UPR) pathway is crucial for tumorigenesis, mainly by regulating cancer cell stress responses and survival. However, whether UPR factors facilitate cell-cell communication between cancer cells and immune cells to drive cancer progression remains unclear. We found that adenosine 3',5'-monophosphate response element-binding protein 3-like protein 2 (CREB3L2), a noncanonical UPR factor, is overexpressed and activated in triple-negative breast cancer, where its cleavage releases a C-terminal fragment that activates the Hedgehog pathway in neighboring CD8+ T cells.

Immune Cells and Intracerebral Hemorrhage: A Causal Investigation Through Mendelian Randomization.

Brain Behav

January 2025

Department of Neurology, The First Affiliated Hospital, Jinan University, Guangzhou, Guangdong, China.

Background: The involvement of immune cells in the pathophysiology of intracerebral hemorrhage (ICH) is becoming increasingly recognized, yet their specific causal contributions remain uncertain. The objective of this research is to uncover the potential causal interactions between diverse immune cells and ICH using Mendelian randomization (MR) analysis.

Methods: Genetic variants associated with 731 immune cell traits were sourced from a comprehensive genome-wide association study (GWAS) involving 3757 participants.

Merkel cell carcinoma (MCC) is a skin cancer that arises due to either Merkel cell polyomavirus infection (MCPyV) or ultraviolet (UV) radiation exposure, presenting primarily in the head and neck region of fair-skinned males. The recent success of PD-(L)1 immune checkpoint inhibitors (ICIs) in locally advanced/metastatic MCC, with an objective response rate (ORR) around 50% and improved survival, as a first-line treatment has moved ICIs to the forefront of therapy for MCC and generated interest in identifying biomarkers to predict clinical response. The MCC tumour microenvironment (TME) contains various components of the adaptive and innate immune system.
