The preferred SSOs according to the invention target exon 7 of TNFR1 (TNFRSF1A) or TNFR2 (TNFRSF1A) pre-mRNA, typically resulting in the production of TNFR variants which comprise a deletion in part or the entire exon 7 respectfully. SSOs targeting exon 7 are found to result in a soluble form of the TNFR, which has therapeutic benefit for treatment of inflammatory diseases. The SSO's are characterized in that they are substantially incapable or incapable of recruiting RNaseH.
