66 results about "Constitutively active" patented technology

Constitutively active: A constitutively active gene is always transcribed, regardless of any regulatory influences. Many, perhaps most genes are constitutively transcribed at some (possibly low) level; however, the level of transcription can be turned up or down by the action of regulatory genes. []

Enhancing the t-cells stimulatory capacity of human antigen presenting cells and their use in vaccination

With the current invention, we provide new methods of enhancing the T-cell stimulatory capacity of human dendritic cells (DCs) and their use in cancer vaccination. The method comprises the introduction of different molecular adjuvants to human DCs through transfection with at least two mRNA or DNA molecules encoding markers selected from the group of: CD40L, CD70, constitutively active TLR4 (caTLR4), IL-12p70, EL-selectin, CCR7 and / or 4-1 BBL; or in combination with inhibition of SOCS, A20, PD-L1 and / or STAT3 expression, for example through siRNA transfection. We could show a clear increase in the immunostimulatory capacity of DCs obtained in this way, enabling them to elicit an unexpectedly high T-cell immune response in vitro. Introduction of at least two of the above molecules, in combination with a tumor-specific antigen enables the DCs to elicit a significant host-mediated T-cell immune response in vivo against the tumor antigen and thus makes them very attractive in the manufacturing of anti-cancer vaccines.

Methods and compositions for preserving the viability of photoreceptor cells

Provided are methods and compositions for maintaining the viability of photoreceptor cells following retinal detachment. The viability of photoreceptor cells can be preserved by administering a neuroprotective agent, for example, a substance capable of suppressing endogenous calcineurin or constitutively active calcineurin, inhibiting cleavage of calcineurin to constitutively active calcineurin, and / or directly or indirectly antagonizing calcineurin or constitutively active calcineurin (and combinations thereof), to a mammal having an eye with retinal detachment. The neuroprotective agent maintains the viability of the photoreceptor cells until such time that the retina becomes reattached to the underlying retinal pigment epithelium and choroid. The treatment minimizes the loss of vision, which otherwise may occur as a result of retinal detachment.

Gene Delivery Vehicles in the Treatment of Neurodegenerative Diseases

ActiveUS20140100265A1Promoting axon regenerationSugar derivativesPeptide/protein ingredientsGene deliveryAxon growth
Currently no therapies that provide either protection or restoration of neuronal function for adult onset neurodegenerative diseases such as Parkinson's disease exist. Many clinical efforts to provide such benefits by infusion of neurotropic factors have failed. An alternative approach such as viral construct transduction may be used to directly activate the intracellular signaling pathways that mediate neurotrophic effects and induce axon growth. Viral construct transduction of dopaminergic neurons with a constitutively active human form of the p70S6K gene—hp70S6K (CA)—was shown to induce axon regeneration from living dopaminergic cell bodies that had no living axons.

Treatment of Human Multiple Myeloma by Curcumin

All multiple myeloma cell lines examined showed constitutively active IκB kinase (IKK), IκBα phosphorylation and constitutively active NF-κB. Curcumin, a chemopreventive agent, suppressed constitutive IκBα phosphorylation through inhibition of IKK activity and downregulated NF-κB. Curcumin also downregulated expression of NF-κB-regulated gene products such as IκBα, Bcl-2, Bcl-xL, cyclin D1 and interleukin-6. Consequently, curcumin suppressed multiple myeloma cell proliferation and arrested cells at the G1 / S phase of the cell cycle. Curcumin also induced apoptosis and chemosensitivity to vincristine. Overall, results presented herein provide a molecular basis for the treatment of multiple myeloma patients with this pharmacologically safe agent.
