Methods and compositions are disclosed for controlling expression of TNF
receptors (TNFR1 and TNFR2) and of other receptors in the TNFR
superfamily using compounds that modulate splicing of pre-mRNA encoding
these receptors. More specifically these compounds cause the removal of
the transmembrane domains of these receptors and produce soluble forms of
the receptor which act as an antagonist to reduce TNF-.alpha. activity or
activity of the relevant ligand. Reducing TNF-.alpha. activity provides a
method of treating or ameliorating inflammatory diseases or conditions
associated with TNF-.alpha. activity. Similarly, diseases associated with
other ligands can be treated in like manner. In particular, the compounds
of the invention are splice-splice switching oligomers (SSOs) which are
small molecules that are stable in vivo, hybridize to the RNA in a
sequence specific manner and, in conjunction with their target, are not
degraded by RNAse H.
