106 results about "TLR9" patented technology

Toll-like receptor 9 is a protein that in humans is encoded by the TLR9 gene. TLR9 has also been designated as CD289 (cluster of differentiation 289). It is a member of the toll-like receptor (TLR) family. TLR9 is an important receptor expressed in immune system cells including dendritic cells, macrophages, natural killer cells, and other antigen presenting cells. TLR9 preferentially binds DNA present in bacteria and viruses, and triggers signaling cascades that lead to a pro-inflammatory cytokine response. Cancer, infection, and tissue damage can all modulate TLR9 expression and activation. TLR9 is also an important factor in autoimmune diseases, and there is active research into synthetic TLR9 agonists and antagonists that help regulate autoimmune inflammation.

The present disclosure provides methods of inhibiting an immune response to a viral vector used in gene therapy, such as adeno-associated virus (AAV), which involves co-administration of viral vector and an interfering molecule. The interfering molecule functions by either disrupting the TLR9-MyD88-type I IFN signaling pathway and / or neutralizing Type I IFNs, thereby inhibiting the immune response directed against the viral vector. The methods additionally encompass the step of re-administering the viral vector.

Regulation of toll-like receptors on stem cells

The discovery of Toll-like receptors (TLRs) on the surface of hematopoietic cells provides new methods for the stimulation and differentiation of various classes of progenitor cells. TLR2 and TLR4 agonists (natural ligands, mimetics, antibodies) are particularly useful in these methods. The cells can be isolated and used for various purpose including tissue regeneration and grafting. In contrast, antagonists of TLRs can be used to protect cells from various insults such as chemo- and radiotherapy, acute and chronic infection, and transplantation by inhibiting activation and differentiation. TLR2, TLR4 and TLR9 pathway antagonists (soluble TLR, mimetics, antibodies) are particularly useful in these methods. Cells can be isolated and used for various purposes including transplantation.
