Despite exhaustive efforts, progress in gene mapping of fibrosing lung diseases has been very slow. In the last 15 or so years, our knowledge of the association of HLA alleles in SSc and sarcoidosis has improved, but the exact mechanism involved remains elusive. Results showed in this thesis indicate that in addition to the HLA, co-stimulatory molecules also play an important role in the pathogenesis of these disorders. There is also evidence that genes involved in trafficking of inflammatory cell... Mehr
