Surfactant proteins SP-A and SP-D are hydrophilic, collagen-containing calcium-dependent lectins, which appear to have a range of innate immune functions at pulmonary as well as extrapulmonary sites. These proteins bind to target ligands on pathogens, allergens, and apoptotic cells, via C-terminal homotrimeric carbohydrate recognition domains, while the(More)
Properdin and factor H are two key regulatory proteins having opposite functions in the alternative complement pathway. Properdin up-regulates the alternative pathway by stabilizing the C3bBb complex, whereas factor H downregulates the pathway by promoting proteolytic degradation of C3b. While factor H is mainly produced in the liver, there are several(More)
This chapter examines the use of proteomics in understanding pathogenesis and identifying possible biomarkers in a range of neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease, and prion diseases. We have attempted to look at the neuroproteomic approach from a biomarker discovery(More)
Huntington's disease (HD) is a progressive neurodegenerative disorder that is caused by abnormal expansion of CAG trinucleotide repeats. Neuroinflammation is a typical feature of most neurodegenerative diseases that leads to an array of pathological changes within the affected areas in the brain. The neurodegeneration in HD is also caused by aberrant immune(More)
The family of NFAT (Nuclear Factor of Activated T-cells) transcription factors plays an important role in cytokine gene regulation. In peripheral T-cells, NFATc1 and c2 are predominantly expressed. Due to different promoter and polyA site usage as well as alternative splicing events, NFATc1 is synthesized in multiple isoforms. The highly inducible NF-ATc1/A(More)
