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.

An astrocyte-specific drug carrier containing a retinoid derivative and/or a vitamin A analog as a constituent; a drug delivery method with the use of the same; a drug containing the same; and a therapeutic method with the use of the drug. By binding a drug carrier to a retinoid derivative such as vitamin A or a vitamin A analog or encapsulating the same in the drug carrier, a drug for therapeutic use can be delivered specifically to astrocytes. As a result, an astrocyte-related disease can be efficiently and effectively inhibited or prevented while minimizing side effects. As the drug inhibiting the activity or growth of astrocytes, for example, a siRNA against HSP47 which is a collagen-specific molecule chaperone may be encapsulated in the drug carrier. Thus, the secretion of type I to type IV collagens can be inhibited at the same time and, in its turn, fibrosis can be effectively inhibited.
