The present invention relates to methods for modulating Toll-like receptor signalling in a subject, or in at least one cell, tissue or organ thereof, methods for treating or preventing a disease or condition in a subject, methods for modulating the production and/or secretion of one or more immunomodulators in a subject, or at least one cell, tissue or organ thereof, wherein said methods involve the administration of chaperonin 10, and wherein the chaperonin 10 associates with a Toll-like receptor in an activation cluster. Also contemplated are associated compositions and uses thereof.

Chaperonin 10-induced immunomodulation

The present invention relates to isolated Chaperonin 10 polypeptides possessing immunomodulatory activity, but lacking, or substantially lacking, protein folding activity.

Modified chaperonin 10

The present invention relates to the use of chaperonin 10 to modulate the function of antigen presenting cells. More particularly the invention resides in the modulation of cell surface expression of MHC molecules such as HLA.

Regulation of immune responses by modulation of the function of antigen presenting cells

A novel granule dispersion composition which comprises water and, dispersed therein, a finely pulverized, sparingly water-soluble substance. The granule dispersion composition is prepared by dispersing in water a granular material which comprises a specific substance sparingly soluble in water, a polymer, and an oil and has an average particle diameter of 1 &#x3bc;m or smaller and in which the ratio of the total weight of the polymer and oil to the weight of the specific substance is 1.5 or higher.

Methods of use of Chaperonin 10 (Cpn10) are provided for regulating Toll-like receptor signaling and/or Toll-like receptor inducible immunomodulator secretion. Cpn10 negatively regulates Toll-like receptor agonist-induced pro-inflammatory cytokine and chemokine secretion, examples being IL-6 and RANTES, respectively. Cpn10 positively regulates Toll-like receptor agonist-induced anti-inflammatory cytokine and chemokine secretion, an example being IL-10. These immunoregulatory activities of Cpn10 may be useful in the treatment of diseases, disorders and conditions resulting from excessive pro-inflammatory cytokine and chemokine secretion. This invention also relates to producing, designing and/or screening Cpn10 agonists and antagonists according to their ability to regulate Toll-like receptor signaling and/or Toll-like receptor inducible immunomodulator secretion.
