Human keratinocytes acquire cellular cytotoxicity under UV-B irradiation. Implication of granzyme B and perforin.

Ultraviolet (UV) radiation from the sun is widely considered as a major cause of human skin photoaging and skin cancer. Granzyme B (GrB) and perforin (PFN) are two proteins contained in granules and implicated in one of the mechanisms by which cytotoxic lymphocytes and natural killer cells exert their cytotoxicity against virus-infected, alloreactive, or transformed cells. The distribution of G...

Nrf2-mediated protection against UVA radiation in human skin keratinocytes.

Ultraviolet A (UVA, 320-400 nm) radiation is an oxidizing agent that causes significant damage to cellular components and that leads to photoaging and cancer. It strongly induces NF-E2-related factor 2 (Nrf2) expressions in cultured FEK4 human skin fibroblasts but weakly induces it in transformed HaCaT skin keratinocytes. Nrf2 silencing increases cell damage at a moderate dose of UVA irradiatio...

Pet Induces IL1, TNF , MIF and IL1Ra Through the IKK /NF B Pathway

Plasmid encoded protein (Pet), a product of E. coli, infiltrates leukocyte in experimental models and acts on macrophages as a chemokine. As an immune response orchestrator, macrophages play an important role in inducing proinflammatory cytokines. In this work, we tested whether in macrophages Pet stimulates the expression of IL1, TNF , MIF and the antagonist IL1Ra. We also sought the IKK /NF B...

Methotrexate induces differentiation of human keratinocytes.

Terminal differentiation is a key element in the maintenance of tissue homeostasis in the epidermis. We show here that methotrexate (MTX) induces differentiation of human epidermal keratinocytes in vitro. MTX inhibits proliferation of keratinocytes and also induces several markers of differentiation: a change in cell morphology, a marked increase in cell size, an increase in the proportion of c...

Granzyme B mediates neurotoxicity through a G-protein-coupled receptor.

Neuroinflammatory diseases such as multiple sclerosis (MS) are characterized by focal regions of demyelination and axonal loss associated with infiltrating T cells. However, the role of activated T cells in causing neuronal injury remains unclear. CD4 and CD8 T cells were isolated from normal donors and polyclonally activated using plate-bound anti-CD3 and soluble anti-CD28. The conditioned T c...
