It weighs around 43 kDa and is primarily expressed in pulmonary alveoli where lung cells synthesize it. SP-D belongs to the collectin family and has a C-type lectin domain that allows binding to carbohydrate structures on microbial surfaces. This ability enables SP-D to interact directly with various pathogens and infected cells targeting them for clearance. Researchers often study SP-D with 'anti-surfactant' antibodies using methods like the ELISA protocol including versions like ELISA Sp and ELISA Denise.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nSP-D contributes to host defense by enhancing the uptake and elimination of pathogens by immune cells such as macrophages. Part of a larger protein complex SP-D can opsonize bacteria and viruses facilitating phagocytosis. Its role extends to modulating inflammation by affecting the production of pro-inflammatory cytokines. By maintaining homeostasis in surfactant composition it indirectly supports lung function and protects against lung injury. SP-D’s function involves communication and transmission of signals within the immune system making it integral to pulmonary immune processes.\u003cbr\u003e\nPathways\u003cbr\u003e\nSurfactant protein D is involved in the regulation of the complement and coagulation cascades as well as the pathogen recognition pathway. It is closely related to other collectins such as surfactant protein A (SP-A) which share similar mechanisms in the immune response. SP-D's interaction within these pathways highlights its role in identifying and neutralizing pathogens. Through its connections with related proteins SP-D plays an important part in modulating immune responses ensuring effective pathogen elimination without excessive inflammation.\u003cbr\u003e\nSP-D has been linked with respiratory diseases such as chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis. These conditions may involve impaired SP-D function or expression levels potentially due to genetic factors or environmental influences. SP-D also interacts with proteins like SP-A in these diseases participating in lung immune responses. Disrupted regulation of SP-D can contribute to chronic inflammatory states in the lungs exacerbating disease progression and leading to compromised lung function. Understanding SP-D's role in these contexts offers potential therapeutic insights for targeting pathological inflammation.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843560493225,"sku":"ab240683","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab240683","provider":"Iright","version":"1.0","type":"link"}
