Introduction to autophagy signaling pathway

Based on Luminex technology platform, Creative Proteomics provides analysis services for key targets of autophagy signaling pathway.

Autophagy Signaling Pathway Detection ServiceAutophagy-related proteins (ATG) regulate this process in yeast and many ATG proteins are conserved in mammals. Individual ATG proteins and ATG-complexes support specific steps in the dynamic process of autophagy. The formation of a double membrane vesicle for the entrapment and delivery of cytosolic content to lysosomes is the hallmark of autophagy. Formation of the mature organelle or autolysosome involves a sequence of coordinated events. In each step, ATG proteins catalyze specific reactions critical for the maintenance of autophagic flux.

Autophagy has recently been shown to be an important component of the innate immune response. The signaling pathways leading to activation of autophagy in innate immunity are not well studied.Recent study shows that Toll-like receptor 4 (TLR 4) serves as an environmental sensor for autophagy. Defined a new molecular pathway in which lipopolysaccharide (LPS) induces autophagy in human and murine macrophages by a pathway regulated through Toll-interleukin 1 receptor domain-containing adaptor-inducing interferon-β (TRIF)-dependent, myeloid differentiation factor 88 (MyD88)-independent TLR4 signaling. Receptor-interacting protein (RIP1) and p38 mitogen-activated protein-kinase (MAPK) are downstream components of this pathway. This signaling pathway does not affect cell viability, indicating that it is distinct from an autophagic death signaling pathway. Further show that LPS-induced autophagy can enhance mycobacterial co-localization with the autophagosomes.

Technology platform:

We provide Luminex technology for autophagy signaling pathway analysis.

Luminex technology is a multifunctional liquid phase analysis platform developed on the basis of colored microspheres, laser technology, applied fluidics and high-speed digital signal processing technology. The core is to encode polypropylene microspheres or magnetic microspheres with fluorescent dyes. By adjusting the different ratios of the two fluorescent dyes, up to 100 microspheres with different fluorescence spectra can be obtained. Antigen-antibody, enzyme-substrate, ligand-receptor binding reactions and nucleic acid hybridization reactions are performed on microspheres with different fluorescence encoding. Qualitative and quantitative analysis by laser detection of microsphere coding and reporter fluorescence separately.

The hallmark of autophagy is the formation of double-membrane vesicles, which are used to trap cytoplasmic content in the lysosome and deliver it to the lysosome. Autophagy signaling proteins play a vital role in maintaining autophagy flux, regulating innate immunity, and removing pathogens.

In addition to Luminex Multiplex Assay, Enzyme-linked immunosorbent assay (ELISA), Flow cytometry (FACS analysis) technology can also be provided to meet other customer needs.
