Summary
Osteopontin (OPN) is newly found in psoriasis patients' blood and skin. This immune molecule may be a therapeutic target for treating psoriasis inflammation.
Area of Science:
- Immunology
- Dermatology
- Molecular Biology
Background:
- Osteopontin (OPN) is a glycoprotein involved in immune responses and inflammation.
- OPN's role in psoriasis pathogenesis was previously uninvestigated.
- OPN influences T-helper cell cytokine expression, impacting immune balance.
Purpose of the Study:
- To investigate the expression and role of Osteopontin (OPN) in psoriasis.
- To determine if OPN is present in psoriatic lesions and peripheral blood.
- To explore OPN as a potential therapeutic target for psoriasis.
Main Methods:
- Collected blood and skin samples from 30 plaque psoriasis patients and 11 healthy donors.
- Included atopic dermatitis samples as a control for Th2-mediated skin disease.
- Analyzed cytokine profiles (IL-1beta, IFN-gamma, TNF-alpha, IL-8) and ICAM-1 expression.
Main Results:
- Osteopontin (OPN) was detected in peripheral blood mononuclear cells and skin biopsies of psoriatic patients.
- Psoriatic samples exhibited a characteristic Th1 inflammatory pattern.
- Specific inflammatory markers associated with Th1 response were identified.
Conclusions:
- Osteopontin (OPN) is expressed in psoriasis and correlates with Th1-type inflammation.
- OPN may play a significant role in the inflammatory processes of psoriasis.
- OPN represents a promising potential therapeutic target for psoriasis intervention.

EPS 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,...
Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
Proteoglycans
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...
Role Of Notch Signalling In Intestinal Stem Cell Renewal
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Phosphoinositides and PIPs
Phosphoinositides are a group of phospholipids containing a glycerol backbone with two fatty acid chains and a phosphate attached to a myoinositol sugar ring. The inositol head group extends into the cytoplasm, where it is modified by adding phosphate groups to form phosphatidylinositol phosphates or PIPs.
Different phosphoinositides are synthesized and recruited on the cytosolic face of the plasma membrane. The localization of specific phosphoinositides concentrated in separate membrane...

Clinical Applications of Epidermal Stem Cells
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 EpiSCs...
