Manganese superoxide dismutase and catalase are coordinately expressed in the alveolar region in chronic interstitial pneumonias and granulomatous diseases of the lung.
Our results show a probable influence of gene polymorphisms, namely IL-4R alpha and IL-10 on ENA-78 BALF levels in sarcoidosis, IL-6 on ENA-78 BALF levels in HP and IL-1-beta on IL-1RA BALF values in the IPF group.
The minor allele of the MUC5Brs35705950 genotype is prevalent in several sporadic forms of ILD, including idiopathic pulmonary fibrosis and chronic hypersensitivity pneumonitis.
The MUC5B promoter variant rs5705950, telomerase complex mutations and short telomere lengths are also linked to an increased susceptibility to pulmonary fibrosis in RA and chronic hypersensitivity pneumonitis.

The minor allele frequency (MAF) was greater for MUC5Brs35705950 in patients with chronic hypersensitivity pneumonitis than in healthy controls (24·4% in UCSF and 32·3% in UTSW vs 10·7%, both p<0·0001), but not for TOLLIP rs5743890.
Genetic susceptibility to multicase hypersensitivity pneumonitis is associated with the TNF-238 GG genotype of the promoter region and HLA-DRB1*04 bearing HLA haplotypes.
Since tumor necrosis factor (TNF)-alpha is thought to be involved in the pathogenesis of HP, and polymorphisms in the TNF genes have been associated with variations in the production of TNF-alpha, we investigated the serum bioactivity and genotype of TNF in HP.
This study demonstrated that peptides from microorganisms involved in HP were able to induce a high IFNγ specific immune response after stimulation of PBMCs from healthy blood donors which could be useful to develop an effective prevention strategy.
The CCL8 concentrations in BAL fluid was significantly higher in 86 patients with IPF than those in 41 controls, and other interstitial lung diseases including non-specific interstitial pneumonia (n = 22), hypersensitivity pneumonitis (n = 20) and sarcoidosis (n = 19) (p < 0.005, respectively).

We found that the neutralization of IL-17A by the antibody attenuated granuloma formation and the recruitment of neutrophils, and also decreased the expression level of chemokine(C-X-C motif) ligand 5 (CXCL5) in the acute HP model.
Our results show a probable influence of gene polymorphisms, namely IL-4R alpha and IL-10 on ENA-78 BALF levels in sarcoidosis, IL-6 on ENA-78 BALF levels in HP and IL-1-beta on IL-1RA BALF values in the IPF group.
These results are consistent with previous observations of a paucity of INFgamma and a predominantly type II (Th2-like) pattern of immune response in patients with CFA and suggest a possible imbalance of pro-fibrogenic cytokines in the distal lung of patients with this condition, compared with those with EAA or sarcoid.
Free mtDNA was found elevated in other ILDs with low expression of PINK1 including hypersensitivity pneumonitis and autoimmune interstitial lung diseases.
