Summary
Certain human leucocyte antigen (HLA) gene variations, specifically HLA-B*37:01 and HLA-DRB1*11:06, are associated with an increased risk of ischemic stroke (IS). These findings highlight the genetic role of HLA in IS development.
Area of Science:
- Immunogenetics
- Neurology
- Molecular Biology
Context:
- Ischemic stroke (IS) is a significant health concern with complex etiology.
- The human leucocyte antigen (HLA) system plays a crucial role in immune responses and has been implicated in various diseases.
Purpose:
- To investigate the potential association between specific human leucocyte antigen (HLA) gene polymorphisms and the risk of developing ischemic stroke (IS).
Summary:
- This study analyzed HLA-A, -B, -C, -DRB1, and -DQB1 alleles and haplotypes in 94 IS patients and 503 healthy controls using PCR-SBT.
- Significantly higher frequencies of HLA-A*31:01, HLA-B*37:01, and HLA-DRB1*11:06 alleles were observed in IS patients compared to controls.
- The HLA-DRB1*11:06-DQB1*03:01 haplotype was also found at a higher frequency in the IS group.
Impact:
- Identifies specific HLA alleles (HLA-B*37:01, HLA-DRB1*11:06) and a haplotype (HLA-DRB1*11:06-DQB1*03:01) as potential genetic risk factors for ischemic stroke.
- Contributes to understanding the genetic underpinnings of ischemic stroke.
- May inform future research into targeted prevention or treatment strategies based on genetic predisposition.

12.6K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

The pharmacogenetics of drug transporters is increasingly recognized as a critical factor influencing interindividual variability in drug absorption, distribution, and elimination. These membrane-bound proteins regulate drugs' movement across cellular barriers by actively pumping them out (efflux) or facilitating their uptake (influx). Among the major transporter families, ATP-binding cassette (ABC) and solute carrier (SLC) transporters play particularly prominent roles. Genetic polymorphisms...

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

01:15Ischemic Stroke ll: Pathophysiology
54
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

01:15Ischemic Stroke l: Introduction
44
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.

Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...
