Summary
Psoriasis, a chronic skin disorder, affects 2% of Caucasians. Research explores its genetic basis and environmental factors, identifying numerous chromosomal regions linked to the disease.
Area of Science:
- Dermatology
- Genetics
- Immunology
Background:
- Psoriasis is a prevalent, chronic, hyperproliferative inflammatory skin disorder affecting approximately 2% of Caucasians.
- Significant variations in psoriasis incidence exist across different ethnic populations, suggesting complex genetic and environmental influences.
- While numerous chromosomal regions (loci) have been implicated through genomewide scans, specific susceptibility genes remain poorly identified.
Purpose of the Study:
- To review the genetic basis of psoriasis.
- To discuss the results and interpretations of relevant genetic studies.
- To highlight challenges and future perspectives in mapping genes for complex diseases like psoriasis.
Main Methods:
- Review of existing literature and genomewide scan data.
- Analysis of genetic and environmental factors contributing to psoriasis.
- Discussion of study designs and their impact on genetic mapping.
Main Results:
- Multiple chromosomal regions are associated with psoriasis susceptibility.
- The genetic architecture of psoriasis is complex, involving numerous loci.
- Environmental factors likely play a role in disease incidence variations.
Conclusions:
- Identifying genes contributing to complex diseases like psoriasis remains a significant challenge in the post-genomic era.
- Further research is needed to elucidate the specific genetic underpinnings of psoriasis.
- Improved study designs are crucial for advancing our understanding of psoriasis genetics.

01:29Pharmacogenomics: Identification of New Drug Targets
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
01:21EPS and iPS Cells in Disease Research
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...
01:22iPS Cell Differentiation
The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.
01:29Microorganisms in Medicine and Therapeutics
Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
01:11Genome-wide Association Studies-GWAS
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.
