Epigenetics in Immune-Mediated Disease

 pigenetics can be defined as the collective modifications in the chemical structure of DNA and histone proteins, without altering the basic DNA nucleotide sequence. This can result in changes in gene expression primarily via regulating chromatin accessibility. Gene expression can also be altered by non-coding RNAs which have been increasingly recognized to be expressed throughout the genome. Understanding epigenetic modifications and the functional implications of individual epigenetic marks has helped to illuminate the complexity of mammalian genomes and has provided important insights into the regulatory role of intergenic and non-protein-coding genomic regions. 


In addition, genetic-epigenetic interaction, whereby disease-associated genetic variants directly or indirectly influence locus-specific epigenetic modifications, can provide mechanistic implications for disease-associated genetic variants in immune-mediated diseases.

Protective HLA Alleles Recruit Biased and for the most part Similar Antigen-Specific T cell Repertoires across completely different Outcomes in HIV Infection.

CD8+ T cells play a very important role within the management of untreated HIV infection. many studies have advised a decisive role of TCRs concerned in anti-HIV immunity. HLA-B*27 and B*57 area unit typically related to a delayed HIV malady progression, however the precise correlates that offer superior immunity against HIV aren't legendary. to research if the T cell repertoire underlies the protecting impact in malady outcome in HLA-B*27 and B*57+ people, we tend to analyzed Ag-specific TCR profiles from progressors (n = 13) and slow progressors (n = 11) expressing either B*27 or B*57. Our knowledge showed no variations in TCR diversity between progressors and slow progressors. each alleles recruit biased T cell repertoires (i.e., TCR populations inclined toward specific TRBV families or CDR3 regions). This bias was unrelated to malady progression and was remarkably profound for HLA-B*57, within which TRBV family usage and CDR3 sequences were shared to some extent even between ep...

Tumor-agnostic treatment treatments approved

Image
  Tumor-agnostic treatment is a drug treatment that is used to treat any kind of cancer, regardless of where in the body it started or the type of tissue from which it developed. This type of treatment can be used when the tumor has a very specific molecular alteration that is targeted by the drug or predicts that the drug is likely to work. Pembrolizumab was the first drug to be approved with a tumor-agnostic indication. Pembrolizumab is a type of immunotherapy, a drug that works by releasing the brakes on the immune system. In 2017, pembrolizumab was approved by the FDA to treat adults and children with solid tumors that have spread, called metastatic, or that cannot be treated with surgery, called unresectable. These tumors must also have a molecular alteration called microsatellite instability-high (MSI-H) or DNA mismatch repair deficiency (dMMR). Tumors that have MSI-H or dMMR have difficulty repairing damage to their DNA. As a result, they often develop large numbers of mut...

The mortal Dendritic Cell Atlas An Integrated Transcriptional Tool to Study Human Dendritic Cell Biology.

Image
Dendritic cells( DCs) are functionally different and are present in utmost adult apkins, but deep understanding of mortal DC biology is hampered by fairly small figures of these in rotation and their short lifetime in mortal apkins. We erected a transcriptional atlas of mortal DCs by combining samples from 14 expression profiling studies deduced from 10 laboratories. We linked significant gene expression variation of DC subset – defining labels across towel type and upon viral or bacterial stimulation. We further punctuate critical gaps between in vitro – deduced DC subsets and their in vivo counterparts and give substantiation that monocytes or cord blood ancestor in vitro – discerned DCs fail to capture the force of primary DC subsets or actions. In constructing a reference DC atlas, we give an important resource for the community wishing to identify and annotate towel-specific DC subsets from single- cell datasets, or standard new in vitro models of DC biology.
