Among those persons who died with dementia, the distribution of Alzheimer’s-type pathological features remained roughly continuous with increasing age, and consequently there was a decline in the association between the burden of Alzheimer’s-type pathological features and dementia. With raising age, there exists a decrease in the opportunity to predict dementia based on the burden of neuritic plaques in the hippocampus and neocortex and of neurofibrillary tangles in the hippocampus. Neuropathological validation of the medical diagnosis of Alzheimer’s disease, predicated on confirmation of the presence of these changes, has a different meaning in the oldest previous, because that same burden of pathological features may regularly be within people of the same age who do not have dementia.The brand new pre-clinical research findings, october 6 – 8 offered at the 9th Annual Interacting with of the Oligonucleotide Therapeutics Culture being kept, 2013 in Naples, Italy, show that subcutaneous administration of a GalNAc-siRNA targeting ALAS-1 leads to quick, dose-dependent, and long-long lasting knockdown of ALAS-1 mRNA and complete inhibition of the toxic intermediates that mediate the symptoms and pathology of AIP. Based on these findings, including results in non-human primate studies, the company has selected its ALN-AS1 Development Applicant and expects to document an Investigational New Drug application because of this RNAi therapeutic in 2014.
