Description

An inflammatory skin condition known as psoriasis is characterised by erythematous, scaly patches on the skin. Psoriasis affects 2%-3% of people worldwide. Psoriasis negatively impacts the patient's health and quality of life, is linked to major medical conditions, and has an impact on family members' quality of life. Psoriasis has an unclear specific origin, however genetic and environmental variables are significant in how it develops. Chronic infections, stress, low humidity, medications (beta-blockers, lithium, antimalarials, and interferon), smoking, and obesity are some environmental factors that appear to affect the course of and susceptibility to psoriasis. These genes are involved in various pathways related to immune function and skin biology. The most well-known genetic risk factor for psoriasis is the HLA-C gene, which is located in the Major Histocompatibility Complex (MHC) region on chromosome.

Variations in this gene increase the risk of developing psoriasis, and certain HLA-C alleles are more strongly associated with the disease than others. Other genes that have been associated with psoriasis include genes involved in the production and activation of T cells, which play a key role in the immune response, as well as genes involved in the regulation of skin cell growth and differentiation. The importance of genetics in illness development has been thoroughly shown in family and twin study. In applicants gene-specific study and Genome Wide Association Studies (GWAS) genetic influences have been thoroughly investigated. The immune system is linked to the genomic regions that are most strongly connected with the onset of the disease. Psoriasis has been closely linked to the Human Leukocyte Antigen Cw6 (HLA-Cw6) and the interleukin 23 receptor of the major histocompatibility complex. Single- Nucleotide Polymorphisms (SNPs) in the promoter region of the Tumour Necrosis Factor gene (TNF) have been identified as performing a significant impact in numerous investigations.

The identification of such widespread connections has led to the development of new, more effective medications with diverse targets, such as the p40 component of IL-12/23 (ustekinumab) and TNF (infliximab, adalimumab, and etanercept). Additional biological medications that target IL17 (ixekizumab and secukinumab) and the IL17 receptor (anti-IL17R) (brodalumab) are being tested in phase III. These medications are all given subcutaneously. Inhibitors of Janus kinase (JAK) and phosphodiesterase 4 (PDE4) (apremilast), which are taken orally and may be less expensive than biological medications, were found to be effective and safe in phase II clinical trials. Although the tolerance and effectiveness of these new medications have improved, development on psoriasis has to advance in order to uncover new oral treatment alternatives that are safer, more efficient, and without harmful side effects. Advances in pharmacogenetics would allow us to customize treatment because it has been shown that genetic variations affect how biological medicines respond in people with psoriasis.

Psoriasis is significantly influenced by the immune system. TNF, IL1, IL12, and IL23 are released by an immunological response that is brought on by macrophage activation. The immune response-related genes TNF, IL12B, and IL23R have been linked to psoriasis. The early differentiation keratinization indicators Involucrin (IVL) and Small Proline-Rich Protein (SPRR) for example, have also been linked to genes that are not connected to immune pathways. These genes are upregulated in psoriasis and are involved in atypical epidermal cellular structure and development. Infliximab, etanercept, and adalimumab are medications that block the effect of TNF, and they have efficacy in treating individuals with inflammatory illnesses like psoriasis. TNF increases IL1 and IL6 production, which in turn suppresses leukocyte movement and the expression of adhesion molecules by endothelial cells and leukocytes. Inflammation is generally reduced when the biological action of TNF is neutralised. New treatment targets and biological medicines are being developed as a result of improvements in our understanding of the metabolic processes involved in the pathogenesis of psoriasis and related illnesses.

The extent of our current knowledge is limited, and several SNPs not connected to the immune system may also contribute to the onset of psoriasis. In order to provide more efficient and secure medications that may be used on an individual basis, larger studies are required to better understand this complicated disease, the pathways involved in its development, and its pharmacogenetic implications. Genetic variables can affect the efficacy and safety of biological therapies. For instance, genetic differences that affect drug transport, metabolism, or target pathways may affect how a patient reacts to therapy with a biological medicine. Additionally, genetic testing can be used to identify patients who are more likely to experience adverse effects from biological drugs, allowing for personalized treatment plans and dosing strategies.
