4986 results about "Cytokine" patented technology

Cytokines are a broad and loose category of small proteins (~5–20 kDa) that are important in cell signaling. Cytokines are peptides, and cannot cross the lipid bilayer of cells to enter the cytoplasm. Cytokines have been shown to be involved in autocrine, paracrine and endocrine signaling as immunomodulating agents. Their definite distinction from hormones is still part of ongoing research. Cytokines include chemokines, interferons, interleukins, lymphokines, and tumour necrosis factors, but generally not hormones or growth factors (despite some overlap in the terminology). Cytokines are produced by a broad range of cells, including immune cells like macrophages, B lymphocytes, T lymphocytes and mast cells, as well as endothelial cells, fibroblasts, and various stromal cells; a given cytokine may be produced by more than one type of cell.

Multipurpose antibody derivatives

The present invention relates to a class of molecules specified as novel multipurpose antibody derivatives. This class of molecules is created by heterodimerization of two constituting components. Heterodimerization is obtained by the specific heterotypic interaction of a chosen VH-CH1 combination of immunoglobulin domains, with a chosen VL-CL combination of immunoglobulin domains. The appropriate VH and VL domains in the VHCH1 and VLCL context, a binding specificity can be constitituted by the heterodimerization scaffold itself. One or both of the comprising VHCH1 and VLCL chains can thus be extended at either the N- or the C-terminus or both with other molecules, such as a toxin polypeptide, an enzyme, a hormone, a cytokine, a signaling molecule, or a single chain linked Fv fragment with the same or a different specificity.

Non-invasive treatment of neurodegenerative diseases

Methods and devices are disclosed for the non-invasive treatment of neurodegenerative diseases through delivery of energy to target nervous tissue, particularly the vagus nerve. The devices include a magnetic stimulator having coils with toroidal windings, which are in contact with an electrically conducting medium that is adapted to conform to the contour of a target body surface of a patient. The coils induce an electric current and / or an electric field within the patient, thereby stimulating nerve fibers within the patient. The stimulation brings about reduction of neuroinflammation in patients suffering from conditions comprising Alzheimer's Disease, Parkinson's Disease, Multiple Sclerosis, postoperative cognitive dysfunction and postoperative delirium. Reduction in inflammation is effected by enhancing the anti-inflammatory competence of cytokines such as TGF-beta, wherein a retinoid or components of the retinoic acid signaling system provide an anti-inflammatory bias, by enhancing anti-inflammatory activity of a neurotrophic factor such as NGF, GDNF, BDNF, or MANF, and / or by inhibiting the activity of pro-inflammatory cytokines such as TNF-alpha.
