Immunocompetent Mice As a Model for Preclinical Studies of mRNA Vaccine Immunogenicity
Doklady Biochemistry and Biophysics. 2023. Vol. 512. No. 1. P. 266–269.
Conducting preclinical studies of mRNA vaccines is complicated by the lack of relevant animal models of the human immune system. Immunocompetent mice are widely used in biomedical research. However, critical differences in the genetics and immune system of mice and humans prevent the study of unique human immune responses in mice. Within the framework of this work, the possibility of modeling the cytotoxic T-cell response to mRNA vaccines encoding the S-protein of the SARS-CoV-2 virus was investigated. High-affinity peptides from S-protein were analyzed for the most frequent allelic variants of human MHC-I, two immunocompetent mouse lines (C57BL/6, BALB/c) and an outbred mouse model of IRC. The results of computer modeling have shown that mouse models can be used in preclinical studies of mRNA vaccines against SARS-CoV-2. Mouse MHC-I is able to present virus peptides that are highly affine for human MHC-I. Moreover, the immunogenicity of some of them has already been confirmed by examining blood samples from patients who have had COVID-19.

The double-stranded RNA editing enzyme ADAR1 connects two forms of genetic programming, one based on codons and the other on flipons. ADAR1 recodes codons in pre-mRNA by deaminating adenosine to form inosine, which is translated as guanosine. ADAR1 also plays essential roles in the immune defense against viruses and cancers by recognizing left-handed Z-DNA and ...

Drosophila homeotic gene Abdominal-B (Abd-B) is controlled throughout development by four infraabdominal (iab) regulatory domains, the active or repressed state of which is determined by initiators that have parasegment-specific enhancer activity at an early stage of embryonic development. For this reason, it has long been assumed that the enhancer activity and initiation function of these elements are synonymous. ...

The specification of abdominal segments A5 to A9 depends on the expression of Abdominal-B (Abd-B), which is regulated by four infraabdominal domains: iab-5 through iab-8,9. Each iab domain contains an initiation element that determines its active state, along with enhancers responsible for tissue-specific activation of Abd-B. These iab domains function autonomously due to their flanking boundaries, Fab-6, Fab-7 and Fab-8, which both block crosstalk between adjacent iab domains (insulator function) and facilitate long-range ...

Background/Objectives: Transcriptional promoters play an essential role in regulating protein expression. Promoters with weak activity generally lead to low levels of expression, resulting in fewer proteins being produced. At the same time, strong promoters are commonly used in studies using transgenic organisms as model systems. This approach can have various negative consequences for the organism, ...

β-Bungarotoxins (β-BuTx), consisting of covalently bound phospholipase A2 subunit (A-chain), a member of group Ia of secretory phospholipases A2, and non-enzymatic subunit (B-chain) structurally related to Kunitz-type protease inhibitors, block presynaptic neuromuscular transmission via a not completely defined mechanism of action. In vivo physiological studies revealed that the B-chain is targeting voltage-gated potassium channels of not identified subtypes. In our work, six β-BuTx isoforms were ...

Large language models (LLMs) in genomics have successfully predicted various functional genomic elements. While their performance is typically evaluated using genomic benchmark datasets, it remains unclear which LLM is best suited for specific downstream tasks, particularly for generating whole-genome annotations. Current LLMs in genomics fall into three main categories: transformer-based models, long convolution-based models, and state-space models ...

Glioblastomas are the most prevalent primary brain tumors and are associated with a dramatically poor prognosis. Despite an intensive treatment approach, including maximal surgical tumor removal followed by radio- and chemotherapy, the median survival for glioblastoma patients has remained around 18 months for decades. Glioblastoma is distinguished by its highly complex mechanisms of immune evasion ...

Unlike most other brachiopods, craniiforms lack a prominent pedicle, cement to a hard substrate by their ventral valve, and thereby can be easily distinguished in paleontological materials.

Although Brachiopoda represent a relatively small phylum, they exhibit significant morphological diversity. One of the central issues in understanding the evolution of the ancestral brachiopod body plan pertains to the homologies among body compartments across the different brachiopod subphyla: Craniiformea, Linguliformea, and Rhynchonelliformea. In this context, the pedicle stands out as one of the most ...

Background:
Delay discounting refers to the tendency to choose sooner, smaller rewards over larger, later rewards. Many previous studies link this tendency positively to reward sensitivity, yet the specific mechanisms behind this association remain poorly understood. Reward sensitivity may relate to delay discounting through at least three possible pathways: increased sensitivity to reward size, increased sensitivity ...

perivascular microenvironment increasingly recognized as key contributors to fibrotic remodeling. The urokinase
