Iety of strategies to circumvent restriction from poly-ubiquitination and degradation mechanisms to exclusion and protection mechanisms. It is likely that many more A3 antagonizing measures exist and await discovery. An overall picture is emerging in which the A3 family members, including AID and APOBEC1, provide an overlapping defense against a wide variety of parasitic elements. This is important for controlling endogenous elements, but also for protecting against exogenous viral infections as well as from zoonotic transmissions. Nearly every DNA-based parasite may be susceptible and, if so, invariably evolved at least one protective measure. Many protective measures have been described thus far and undoubtedly several more await discovery. Clearly, there is still much work to be done, and this story has no finite ending.AcknowledgmentsWe thank N. Shaban for assistance with figures.

The concept of neural organization allows for synaptic remodeling as a compensatory mechanism to the early pathobiology of Alzheimer’s disease (AD) in an attempt to maintain brain function and cognition during the onset of dementia. The hippocampus, a crucial component of the medial temporal lobe memory circuit, is affected early in AD and displays synaptic and intraneuronal molecular remodeling against a pathological background of extracellular amyloid-beta (A) deposition and intracellular neurofibrillary tangle (NFT) formation in the early stages of AD. Here we discuss human clinical pathological findings supporting the concept that the hippocampus is capable of neural plasticity during mild cognitive impairment (MCI), a prodromal stage of AD and early stage AD.Correspondence to: Elliott Mufson, Ph.D., Director, Alzheimer’s Disease Research Laboratory, Institutional Professor, Barrow Neurol.Iety of strategies to circumvent restriction from poly-ubiquitination and degradation mechanisms to exclusion and protection mechanisms.
