The September 14-18 ISA symposium has been moved to a virtual platform


As you are all aware, the meeting was postponed from its original March 2020 dates, to September 14-18, 2020 due to the COVID-19 pandemic. Despite our hope for a physical meeting, we realize that this is not possible due to present circumstances - Particularly due to travel restrictions, and also to social distancing guidelines.

The decision has been made to hold the XVII ISA Symposium on a virtual platform, maintaining the week of September 14, 2020. More information to follow.

We regret any inconvenience that this change may cause, and we thank you for your understanding.

Amyloidosis: The Disease What is amyloid?

Amyloid fibrils are structures in which misfolded proteins are deposited in tissue and organs. Different proteins can be deposited as amyloid in various sites of the human body. When in a piece of tissue (a so-called biopsy) these deposits are viewed under a microscope in normal light, the material looks amorphous. However, if the same deposits are viewed under an electron microscope with higher magnification, massive amounts of small non-branching amyloid fibrils can be seen. When a biopsy is stained with Congo red dye, the deposits will stain red. A characteristic feature of amyloid is that these red deposits will turn into apple green if viewed in polarized light. When amyloid deposition leads to signs and symptoms of disease it is called amyloidosis.
