Use of L-α-lysophosphatidylcholine to differentiate monocytes into mature dendritic cells in vitro

摘要

Maturation of dendritic cells in vitrocomprising adding L-alpha -lysophosphatidylcholine (I) to a culture medium containing immature dendritic cells, is new. Independent claims are also included for: (1) differentiation of monocytes into mature dendritic cells in vitroby inducing differentiation of monocytes into dendritic cells in a culture medium in the presence of a differentiation factor and adding (I) to the medium; (2) activation of T lymphocytes in vitroby producing mature dendritic cells as above, adding a biological agent to produce mature dendritic cells directed against the agent, and contacting the dendritic cells with T lymphocytes to produce T lymphocytes directed against the agent; (3) culture medium containing (I) and a differentiation factor for differentiating monocytes into dendritic cells; (4) vaccine comprising (I) and a biological agent; (5) use of (I) as an immune system activating agent for producing medicaments for treating or preventing bacterial, viral, fungal, parasite or yeast infections or cancer; (6) use of a L-alpha -lysophosphatidylcholine inhibitor to produce a medicament for preventing inflammation or combating an inflammatory or autoimmune disease, where the inhibitor is either a lipid emulsion comprising triglycerides, phospholipids and glycerol or a PPAR gamma agonist. ACTIVITY : Antibacterial; Virucide; Fungicide; Antiparasitic; Cytostatic; Antiinflammatory; Immunosuppressive. No biological data is given. MECHANISM OF ACTION : Immunotherapy.
