An orthopoxvirus vector, such as vaccinia, is described in which the A46R protein from vaccinia, or a closely related protein from any orthopoxvirus is not expressed or is expressed but is non-functional. Also described is the use of a vaccinia virus A46R protein or a closely related protein from any orthopoxvirus, or a functional peptide, peptidometic, fragment or derivative thereof, or a DNA vector expressing any of the above in the modulation and/or inhibition of IL1R/TLR superfamily signalling. |
