Summary
Psoriasis involves T cells affecting skin cell turnover and growth. Researchers identified 14 key genes in T cells that influence these changes, offering new insights into psoriasis.
Area of Science:
- Immunology
- Dermatology
- Genetics
Background:
- Psoriasis pathogenesis is linked to T cell activity impacting epidermal turnover and keratinocyte proliferation.
- Understanding genetic differences in T cells from twins can elucidate psoriasis mechanisms.
Purpose of the Study:
- Identify differentially expressed genes (DEGs) in T cells from psoriasis-concordant and discordant monozygotic twins.
- Determine if these DEGs explain T cell-mediated effects on epidermal turnover and keratinocyte proliferation.
Main Methods:
- RNA sequencing and real-time reverse transcription polymerase chain reaction to analyze T cell gene expression.
- Immunohistochemistry and 3H-thymidine incorporation assays to assess T cell impact on keratinocytes.
Main Results:
- Psoriatic T cells decreased epidermal turnover time and affected keratinocyte proliferation.
- Fourteen DEGs involved in cell proliferation and differentiation were identified.
- Specific genes like PPIL1, HSPH1, and SENP3 were differentially expressed in psoriatic T cells.
Conclusions:
- Differential gene expression in T cells contributes to psoriasis development.
- Targeting identified DEGs may offer novel therapeutic strategies for psoriasis.

01:12Renewal of Skin Epidermal Stem Cells
3.3K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

01:24T Cell Types and Functions
3.4K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

01:19Clinical Applications of Epidermal Stem Cells
3.4K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

02:15Replicative Cell Senescence
4.6K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

02:23Abnormal Proliferation
5.4K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...
