Synapse targeting of AβOs involves activation of p75NTR. PubMed:29196815
They revealed increases in AβOs and soluble TNF-R plasma levels that accurately differentiated mild AD patients from control subjects and to some extent from amnestic mild cognitive impairment (aMCI) patients. PubMed:29196815

Recent evidence supports the notion that p75NTR has an intrinsic signaling capacity including: • Sphingolipid metabolism [98–100] • Activation of the JNK pathway [52,54,56,101–103] • Activation of the NF-kappaB pathway [104–109] • Activation of the Akt pathway [110] • Activation of the MAPK pathway [97,111] PubMed:18986241
NGF is synthesized as a precursor (proNGF) molecule that is proteolytically cleaved to a mature biologically active neurotrophin peptide [49]. Mature NGF binds to the TrkA receptor, which stimulates signal transduction pathways mediating the majority of the survival and growth effects of NGF [50], and to the p75NTR receptor, which is a positive modulator of NGF/TrkA binding [50]. However, p75NTR has multiple functions, including apoptotic or cell death actions [51–56], which are dependent upon its interaction with various receptor chaperones [57–59]. PubMed:18986241
It is also important to note that TrkA reduces and p75NTR activates β-secretase strike (BACE) cleavage of the amyloid precursor protein (APP), which requires NGF binding and activation of the second messenger ceramide [66]. Aging may activate beta-amyloid (Ab) generation in the brain by ‘switching’ from TrkA to p75NTR, suggesting that NGF receptor balance is a molecular link between normal aging of the brain and AD in relation to amyloid processing.

CBF tissues harvested from people who died with a clinical diagnosis of no cognitive impairment (NCI), mild cognitive impairment, or AD were immunolabeled for both p75NTR and Rac1b. Rac1b appeared as cytoplasmic diffuse granules, loosely aggregated filaments, or compact spheres in p75NTR-positive NB neurons. Although Rac1b colocalized with tau cytoskeletal markers, the percentage of p75NTR-immunoreactive neurons expressing Rac1b was significantly increased only in AD compared with both mild cognitive impairment and NCI.
