Abstract
Psoriasis is a frequent autoimmune chronic skin disease differentiated by T-Cells agreeable hyperproliferation of epidermal Keratinocytes. The feature of TCells held up Psoriatic scratches is the epidermal penetration of basically oligoclonal CD8+ T-Cells and also of CD4+ T-Cells in the dermis. Psoriatic lesions are sharply distinguished, red and enlarged scratches together with whitish silver scales. In this research article, we propose a mathematical depiction for Psoriasis, involving a set of differential equations, regarding T-Cells, Dendritic Cells, CD8+ T-Cells and epidermal Keratinocytes. Here, we specially introduce the interaction between Dendritic Cells and CD8+ T-Cells to monitor the impact of this interaction upon the system dynamics. We also analyze the mathematical model both in presence and absence of effectiveness of two drugs. We study the system analytically and numerically to comprehend the significance of effectiveness of the drugs, integrated in the model system. Here, we reduce the Keratinocyte population to restrict Psoriasis by applying the combination of two drugs and able to enlighten the perspective of the disease dynamics for Psoriasis.
Highlights
In spite of precise fundamental and experimental studies for more than a few decades, many queries continue relating to Psoriasis
The CD8+ T-Cells free equilibrium point in presence of effectiveness of first drug and absence of effectiveness of second drug is stable if DC population is less than some pre-determined positive value, provided the product of the rate at which CD8+ T-Cell proliferation is stimulated by antigen presenting DCs, average peptide specific T-Cells Receptor (TCR) and average number of the related pMHC complexes per DCs is greater than the rate of interaction between DCs and
The second drug has not any significant impact on the interaction between DCs and CD8+ T-Cells, which are not influenced for change in the value of the model parameters
Summary
In spite of precise fundamental and experimental studies for more than a few decades, many queries continue relating to Psoriasis. Psoriasis has been measured as a dermatological chaos, in which T-Cells and epidermal Keratinocytes perform a relevant pathogenic function. Psoriasis is observed as a widespread inflammatory skin chaos with an inherited contact. It is illustrious through epidermal hyperplasia by means of cellular diffusion of Lymphocytes, Monocytes and Neutrophils [3]. In our present research article, we introduce CD8+ T-Cells population which interacts with DCs in the dynamical system. This interaction leads to generate Keratinocytes, which in turn supports to expand the Keratinocytes growth. We set the drug in that interaction to control the growth of Keratinocytes, whose surplus production directs to create Psoriasis. We study the effectiveness of two drugs on the cell biological scheme to build a comparative analysis for the drugs to restrain the disease
