Influence of external factors on the preservation of human nervous tissue for histological studies: review article
Neuropathological studies are crucial for the new knowledge on pathophysiology and treatment of neurodegenerative diseases, such as Alzheimer's disease and Parkinson's disease. The postmortem brain tissue processing method directly impacts on both the appropriate integrity and the biomolecules detection by different histological and molecular biology techniques. In this review we will discuss topics on the influence of some external factors on the preservation of the brain tissue for histological studies (histochemistry and immunohistochemistry), such as factors either prior or after the death, and the chosen method for the preservation of nervous tissue. By means of a specific example, we propose a strict record of various conditions involved in the method of preservation of nervous tissue, and its correlation with variables that measure the quality of the histological sample as markers of preservation of biological material for further studies.
