Whatever the mechanism of uptake, it is interesting to note that the signaling pathways evoked by the accumulation of intracellular Abeta resemble those evoked by extracellularly applied Abeta: transgenic rats overexpressing Abeta intraneuronally display elevated levels of phosphorylated ERK2 (Echeverria et al., 2004), as do rat hippocampal slices in response to bath-applied Abeta (Dineley et al., 2001). Again, bath-applied Abeta causes an increase in BAX and a decrease in BCL2 expression in neurons or neuronlike cell lines (Koriyama et al., 2003; Clementi et al., 2006). PubMed:19293145
AKT interacts with BAD to regulate apoptosis and, interestingly, also has many interacting partners in the insulin signaling pathway. Abeta increased activity of BAD, lowered the activity of the antiapoptotic protein BCL2, in rat hippocampal neurons in primary culture (Koriyama et al., 2003) and has been shown to be toxic to human neuroblastoma cells by increasing BAX activity and decreasing BCl-2 activity (Clementi et al., 2006).

The AD therapeutic AChE inhibitors donepezil, galantamine, and tacrine increase BCL2 expression when applied to cultured neuronal cells (Arias et al., 2004; Takada-Takatori et al., 2006). In these cells, nicotine promotes cell survival and causes the phosphorylation of the proapoptotic protein Bcl2-associated X protein (BAX), through the PI3K/AKT pathway, reducing the movement of BAX from the cytosol to the mitochondria and inhibiting its apoptotic activity (Xin and Deng, 2005).

The neuroprotective effects of nicotine are blocked by inhibitors of either PI3K or SRC family kinases, and nicotine evokes an increase in levels of phosphorylated AKT, B-cell chronic lymphocytic leukemia/lymphoma (BCL2), and BCL-2-like protein (Shimohama and Kihara, 2001), which are further downstream in the PI3K/AKT pathway (Fig. 3).

It enhances the expression of anti- apoptotic proteins, such as Bcl-2 and Bcl-xL, and down-regulates the expression of Bim, a pro-apoptotic factor, preventing programmed cell death. 90, 100 Estradiol also activates antioxidant systems to protect neuronal cells from apoptosis by upregulating the expression of manganese superoxide dismutase and glutathione peroxidase. 101 PubMed:30444369
The anti-apoptotic effects of NF-κB have been ascribed to its ability to trans-activate the expression of a multitude of anti-apoptotic genes such as Bcl-2, Bcl-XL, and Bfl-1/A1 in the neurons of the amygdala, olfactory bulb, and the CA1/CA3 region of the hippocampus PubMed:28745240
Stimulation of neuronal cells by TNF-α has been shown to upregulate transactivation of anti-apoptotic gene products and neurotrophins such as Bcl-2 and NGF respectively PubMed:25652642
For instance, c-Jun NH 2-terminal kinase 1 (JNK1) may induce autophagy by phosphorylating Bcl-2 or Bim and abolishing their inhibitory effects on autophagy (Luo et al., 2012; Wei et al., 2008). PubMed:23528736
