Rat Pulmonary surfactant-associated protein A,SP-A ELISA Kit

1. SP-A expression was up-regulated in the middle ear effusion of non-typeable Haemophilus influenza otitis media. PMID: 30055742
2. SPA binds dipalmitoyl-phosphatidylcholine, the major surfactant lipid component, but not phosphatidylinositol; SPD exhibits the opposite preference. Data suggest flexibility in a key surface loop supports distinctive lipid binding of SPA; quadruple mutant SPA (E171D/P175E/R197N/K203D) that introduces SPD-like loop-stabilizing Ca2+ binding site in carbohydrate recognition domain exhibits ligand-binding preferences of SPD. PMID: 28719181
3. Downregulation of SP-A expression caused due to silica is an important factor in the occurrence and development of silicosis. PMID: 27660222
4. Liraglutide activates the GLP1 receptor, increasing ACE2 expression, reversing right ventricle hypertrophy, and improving the production of SP-A and SP-B in the lungs of Type 1 Diabetes rats PMID: 26196539
5. Mutations of rat surfactant protein A have distinct effects on its glycosylation, secretion, aggregation and degradation. PMID: 25242514

7. VIP can up-regulate the expression of SP-A in alveolar type II cells. PMID: 21166190
8. NG-nitro-L-arginine can protect the lung from LPS-induced injury by up-regulating the expression of PS. PMID: 20663300
9. A novel role is demonstrated for SP-A in modulating endolysosomal trafficking via Rab7b (but not Rab5 nor Rab11) in primary alveolar macrophages, and the biochemical pathways are defined. PMID: 21248257
10. SP-A stimulates the release of neutrophil chemotactic factor by alveolar type II cells, and this effect is mediated by the receptor for SP-A specifically expressed by these cells. PMID: 20473679
11. VIP elevated SP-A expression in ATII cells which was mediated by enhanced sp-a gene transcription PMID: 20688121
12. crystal structures of calcium-dependent complexes of the C-terminal neck and carbohydrate recognition domain of SP-A with carbohydrates PMID: 21047777
13. The SPA level decreases significantly in acute pulmonary embolism. PMID: 16207426
14. Data suggest that the pathway for secretion of newly synthesized surfactant protein-A is by transfer from the site of synthesis to the storage/secretory organelle prior to lamellar body exocytosis. PMID: 20382745
15. the ability of SP-A to inhibit immune cell activation by Re-LPS may be due to its ability to block the binding of Re-LPS to LBP and prevent the initiation of the LBP/CD14 pathway for inflammatory reactions in the lung. PMID: 12204898
16. SP-A selectively enhances mannose receptor expression on monocyte-derived macrophages, a process involving both the attached sugars and collagen-like domain of SP-A. PMID: 12244146
17. SP-A can reverse the detrimental effects of surfactant oxidation on the biophysical properties of surfactant, by a mechanism that is dependent on interchain disulfide bond formation and the C-terminal domains of the protein. PMID: 12600986
18. SP-A and SP-D are antimicrobial proteins that directly inhibit the growth of Histoplasma capsulatum by increasing permeability of the organism PMID: 12857753
19. blocks secretagogue-stimulated phospholipid release, even in the presence of surfactant-like lipid PMID: 12882765
20. Results suggest that there is no primary deficiency of surfactant proteins A, B, or C in the nitrofen-induced rat model of congenital diaphragmatic hernia. PMID: 12904592
21. Crystal structure of trimeric carbohydrate recognition and neck domains of surfactant protein A PMID: 12913002
22. SP-A enhances the phagocytosis of S. pneumoniae by alveolar macrophages through a CK2-dependent increase of cell surface SR-A localization (scavenger receptor a) PMID: 14993215
23. SP-A and SP-D enhance mannose receptor-mediated phagocytosis of M. avium by macrophages PMID: 15187139
24. Differential allele-specific expression was observed in all tissues studied (OPN) or in all extrapulmonary tissues (SP-A). Double heterozygous rats revealed lack of coordinate allele expression among SP-A, SP-D, and OPN. PMID: 15482851
25. NO mediated the decrease in surfactant protein gene expression PMID: 15640287
26. We suggest that enhanced release of surfactant phospholipids and SP-A represents an early protective response that compensates in part for the inactivation of intraalveolar surfactant in the early phase of IR injury. PMID: 15969762
27. The addition of rat or recombinant rat SP-A to human monocyte-derived macrophages significantly raises the level of cytosolic calcium above baseline within 10 seconds of SP-A addition PMID: 16081790
28. SP-A and Prdx6 directly interact, which provides a mechanism for regulation of the PLA(2) activity of Prdx6 by SP-A PMID: 16330552
29. results indicated SP-A & SP-D have distinct functions in lung homeostasis & the function of the neck domain & carbohydrate recognition domain of SP-D is dependent on its own NH2-terminal & collagenous domains that cannot be complemented by those of SP-A PMID: 16500946
30. Direct effect of SFTPA1 on rat myometrial cells and inhibitory cross talk between SFTPA1 and LPS signals. PMID: 17202387
31. SP-A2 enhances phagocytosis of Pseudomonas aeruginosa by rat alveolar macrophages more than does SP-A1. PMID: 17220308
32. Air spaces of neonatal lungs comprised lower fractions of tubular myelinand increased unilamellar vesicles, which correlated with low SP-A concentrations in lung lavage fluid and increased respiratory rates, respectively PMID: 17469149
33. alterations of surfactant are a consequence of the ventilation strategy that impair the biophysical activity of this material and thereby contribute directly to lung dysfunction over time PMID: 18344412
34. cigarette smoke alone decreases the level of SP-A and that might have an important effect on surfactant metabolism and the host defense functions of surfactant in the peripheral airways PMID: 18480979
35. After OVA challenge alveolar epithelial cells Type II (AEII) show a significantly higher expression of SP-A and SP-D leading also to higher amounts of both SPs in BALF, and macrophages gather predominantly SP-A. PMID: 18802356
