Abstract:

Cystic Fibrosis (CF), the most common autosomal lethal disorder in Caucasians, is caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. Although CF is multi-organ disease, the lung pathology is the chief cause of morbidity and mortality of CF patients. The hallmarks of CF lung disease are respiratory infection by opportunistic pathogens and a deranged inflammatory response. However, clinical and experimental data suggest that CF is a hyperinflammatory disorder which can arise in the absence of infection. Laboratory and animal studies suggest that CFTR is involved in regulating some neutrophil and macrophage functions and indicate that altered properties of immune cells may contribute to the dysregulated inflammation in the CF lung. Moreover, recent investigations point out to the involvement of lymphocyte subpopulations in the onset of an altered immune response to pathogens. The development of novel therapies aimed to reduce the inflammatory and regulate immune responses, including stem cell-based treatment, will be presented.

More about this publication?
  • This journal is devoted to timely reviews of experimental and clinical studies in the field of endocrine, metabolic, and immune disorders. Specific emphasis is placed on humoral and cellular targets for natural, synthetic, and genetically engineered drugs that enhance or impair endocrine, metabolic, and immune parameters and functions. Topics related to the neuroendocrine-immune axis are given special emphasis in view of the growing interest in stress-related, inflammatory, autoimmune, and degenerative disorders.
