On the other hand, the triple positive-CD4+ cells (PMA stimulation) alone or together with the mock/MAB ratio of IL-2+/TNF-α+ CD4 cells could predict MAB-LD in the MAB-Co group or the controls.
<b>Rationale:</b> Augmentation therapy with intravenous AAT (alpha-1 antitrypsin) is the only specific therapy for individuals with pulmonary disease from AAT deficiency (AATD).
<b>Rationale:</b> The association between non-tuberculous mycobacterial lung disease and alpha-1-antitrypsin (AAT) deficiency is likely due, in part, to underlying emphysema or bronchiectasis.
In an analysis of the cases and unmatched controls who did not receive sulfasalazine, an increased risk of PJP was associated with lung disease (3.88, 1.89-7.95) and the use of glucocorticoid (5.71, 2.68-12.19), methotrexate (5.25, 2.01-13.74), and tumor necrosis factor inhibitors (2.32, 1.10-4.93).
Fibroblasts undergoing replicative senescence or transforming growth factor β1-induced senescence and fibroblasts isolated from human subjects with an age-related lung disorder, idiopathic pulmonary fibrosis, secreted higher numbers of EVs than their respective controls.
Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease with a poor prognosis and limited therapies, and transforming growth factor-β1 (TGF-β1) plays a central role in the pathogenesis of IPF.
Increased risk of liver and lung disease has also been reported in heterozygous subjects who carry Z in association with the milder S allele (Glu264Val) or even with wild-type M. However, it is unknown whether Z AAT can co-polymerize with other AAT variants in vivo.
Elevated levels of TGF-β1 are found in patients with acute and chronic lung diseases, and the underlying disease processes are exacerbated by respiratory viral infections.
Patients with alpha-1 antitrypsin (AAT) deficiency develop progressive lung disease due to the loss of AAT's antiprotease function and liver disease due to a toxic gain of function of the common mutant allele.
PM2.5 exposure during pregnancy results in lung inflammation in offspring mediated by increased HMGB1 expression, followed by upregulated IL-1, IL-6 and TNF-α secretions, which may contribute to the development of inflammatory lung diseases in later life.
Alpha-1 antitrypsin (a1AT) deficiency, in its classical form, is an autosomal recessive disease associated with an increased risk of liver disease in adults and children, and with lung disease in adults.
Classical alpha-1 antitrypsin (a1AT) deficiency is an autosomal recessive disease associated with an increased risk of liver disease in adults and children, and with lung disease in adults (Teckman and Jain, Curr Gastroenterol Rep 16(1):367, 2014).
In individuals with AAT deficiency (AATD), AAT is retained in liver cells, which predisposes them to liver disease, and does not reach lung tissues through circulation, where it normally acts as the primary natural regulator of proteolytic activity in the pulmonary tissues, which thus leads to lung disease.
Alpha-1-antitrypsin deficiency (AATD) is a rare inherited condition caused by mutations of the SERPINA1 gene that is associated with the development of a COPD like lung disease.
The concentrations of TNF-α and CXCL8, but not others, were negatively correlated with severity of disease (lung function forced expiratory volume in 1 s) (TNF-α vs. total: r = -0.359, P= 0.002 vs. moderate/severe: r= -0.541, P= 0.001; CXCL8 vs. total: r = -0.327, P= 0.006 vs. moderate/severe: r = -0.625, P= 0.0001, respectively).
The significant Ago2-IP enrichment of targets of these miRNAs related to the TGF-β and/or Wnt pathways (NGF, DLD, HHEX) in TGF-β1-stimulated fibroblasts suggest a role for these miRNAs in lung diseases by affecting lung fibroblast function.
