Oral lichen planus (OLP) is a chronic inflammatory condition with an unclear pathological mechanism. IκB kinase α (IKKα)-regulated mammary serine protease inhibitor (MASPIN) has been shown to mediate inflammation, particularly in cancers. Here, we explored the expression of MASPIN in BACKGROUND
Oral Lichen planus (OLP) is a chronic lesion of the oral mucosa with unknown origin. Basement membrane changes are common in OLP and may be mediated by proteases such as matrix metalloproteinase (MMPs) and mast cell chymase. The aim of our study was to evaluate the level of serum MMP-3 in
Human Hanukah Factor (HuHF) is a trypsinlike serine protease associated with cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells. Employing a radiolabeled RNA probe for the HuHF gene, cells containing HuHF mRNA in situ were detected in skin lesions from patients with a variety of reactive
Human skin fibroblasts were probed for cell surface protease activity. One activity removing dipeptides from the NH2-terminal end of Gly-Pro-pNA was specifically inhibited by di-isopropyl-fluorophosphate (DFP), phenylmethanesulphony fluoride (PMSF), and diprotin A, and thus was identified as
OBJECTIVE
The expression of human neuropsin (KLK8) mRNA in normal and pathological skin samples was analysed and the results compared with those for tissue plasminogen activator (tPA) mRNA.
METHODS
Northern blot and in situ hybridisation analyses of KLK8 mRNA in normal and lesional skin of patients
BACKGROUND
Cathepsin L is a member of papain superfamily. It seems to promote T-cell survival, selection maturation in the thymus and enhance the antigen presentation. Cathepsin L plays an important role in tumor necrosis factors (TNF-α) induced cell death. Also it degrades the tight junction
Lichen planus (LP) is an inflammatory mucocutaneous disease, showing a wide variety of clinical subtypes. The classic presentation of LP involves the appearance of polygonal, flat-topped, violaceous papules and plaques with reticulated white lines, termed "Wickham's striae". Cutaneous lesions tend
BACKGROUND
Oral lichen planus (OLP) is an idiopathic T-cell-mediated mucosal inflammatory disease. Cathepsin K (Cat K) is one of the lysosomal cysteine proteases. It is involved in many pathological conditions, including osteoporosis and cancer. The expression and role of Cat K in OLP are
BACKGROUND
Malignant transformation of Oral Lichen Planus (OLP) remains a much discussed but very less understood realm. Various hypotheses and theories have been put forward to explain the same. Malignant transformation is a complex interplay of epithelial mesenchymal factors acting in tandem. This
Thrombomodulin (TM) is a glycoprotein originally isolated from rabbit lung vasculature and characterized as a natural endothelial anticoagulant. Thrombin binds to TM noncovalently with high affinity. Thrombin-TM complexes can activate protein C efficiently. Activated protein C inactivates factors Va
Epidermal cornified cells are attached to each other with modified desmosomes, namely corneodesmosomes. Changes in the corneodesmosome degradation process influence the total thickness of the stratum corneum and surface appearance of the skin. The major extracellular constituents of corneodesmosomes
A neutral cysteine protease, bleomycin hydrolase (BH), is widely expressed in mammalian tissues, with the skin seeming to contain the highest level. Our previous study revealed that BH transcription is modulated both during differentiation and by cytokines. However, BH involvement in keratinization
Paraneoplastic pemphigus (PNP) is a distinct autoimmune blistering disease that can affect multiple organs other than the skin. It occurs in association with certain neoplasms, among which lymphoproliferative diseases are most commonly associated. The clinical presentation of PNP consists typically
Mast cells are granule-containing secretory cells which are distributed preferentially about the microvascular bed in oral mucosa. This work examined the contribution of mast cell mediators to inflammation in the oral cavity. Mast cells in oral tissues expressed the serine proteases, tryptase and
In order to gain insights into the dynamics of mast cell subpopulations in normal and diseased skin, a novel enzyme-histochemical double and triple staining method was employed that allowed the detection of metachromasia (toluidine blue) and the mast cell proteases tryptase and chymase within the
