Scientific Background:Autophagy is an alternative process of proteasomal degradation for some long-lived proteins or organelles. Alterations in the autophagic-lysosomal compartment have been linked to neuronal death in many neurodegenerative disorders as well as in transmissible neuronal pathologies (prion diseases). Genetic studies in yeast have shown that Autophagy-defective Gene-8 (Atg-8) represents a specific marker for autophagy. Among the four families of mammalian Atg8-related proteins only LC3 (Microtubule-associated Protein1 Light Chain 3) is expressed at sufficient high levels and efficiently recruited to autophagic vesicles in cells and tissues. During autophagy the cytoplasmic form, LC3-I is processed and recruited to autophagosomes, where LC3-II is generated by site specific proteolysis near to the C-terminus. Autophagic vacuoles have been also reported frequently in cardiomyopathies or muscle cells exposed to different experimental settings.

Figure 1: Endogenous LC3 punctae detected using MAb to LC3B (5F10) (Prod. No. ALX-803-080)Method: The majority of LC3 was diffusely localized in unstimulated COS-7 cells, wheres punctated signals of LC3 increase after induction of autophagy by vinblastin stimulation for 2h. Cells were fixed with paraformaldehyde followed by methanol treatment. Cells were permeabilized with 0.3% Triton X-100. (Image courtesy of I. Ciechomska and A.
