Summary
Three novel human leukocyte antigen (HLA) alleles, including HLA-B*56:55:01:02, HLA-C*03:374, and HLA-DPB1*13:01:03, were identified and characterized. These findings expand the known diversity of HLA alleles crucial for immune response.
Area of Science:
- Immunogenetics
- Molecular Biology
Background:
- The human leukocyte antigen (HLA) system plays a critical role in immune regulation and transplantation.
- Continuous discovery of novel HLA alleles is essential for accurate tissue typing and understanding immune diversity.
Purpose of the Study:
- To characterize newly identified human leukocyte antigen (HLA) alleles.
- To contribute to the comprehensive cataloging of HLA genetic variations.
Main Methods:
- Next-Generation Sequencing (NGS) methodology was employed for high-resolution allele characterization.
- Bioinformatic analysis was used to confirm the novelty and define the sequences of the new alleles.
Main Results:
- Three novel HLA alleles were identified and fully characterized: HLA-B*56:55:01:02, HLA-C*03:374, and HLA-DPB1*13:01:03.
- These alleles represent new additions to the known repertoire of HLA class I and class II genes.
Conclusions:
- The characterization of these novel HLA alleles expands the global HLA reference database.
- Accurate identification of HLA alleles is fundamental for immunological studies and clinical applications like transplantation.

98.6K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

7.7K
Carbon-13 is a naturally occurring NMR-active isotope of carbon with a low natural abundance of 1.1%. In contrast, carbon-12 is the most abundant isotope of carbon with zero nuclear spin. Therefore, it is NMR inactive. The gyromagnetic ratio of carbon-13 is smaller than that of protons. As a result, carbon-13 resonance is about 6000 times weaker than proton resonance. For a given magnetic field strength, the resonance frequency of carbon-13 is about one-fourth of the resonance frequency for...

11.8K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Sequences are fundamental mathematical objects consisting of ordered lists of numbers that follow a specific rule or pattern. Sequences are critical in various mathematical concepts, including calculus, series, and number theory. They can model real-world phenomena such as population growth, financial investments, and physical processes like the diminishing height of a bouncing ball.Each number in a sequence is referred to as a term. Typically, the terms are denoted as a1, a2, a3,…, where...

774.7K
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...
