The prevalent features of AD pathogenesis are the appearance of β-amyloid (Aβ) plaques and neurofibrillary tangles, which cause microglial activation, synaptic deficiency, and neuronal loss. Microglia accompanies AD pathological processes and is also linked to cognitive deficits. Purinergic signaling has been shown to play a complex and tight interplay with the chemotaxis, phagocytosis, and production of pro-inflammatory factors in microglia, which is an important mechanism for regulating microglia activation. Here, we review recent evidence for interactions between AD, microglia, and purinergic signaling and find that the purinergic P2 receptors pertinently expressed on microglia are the ionotropic receptors P2X4 and P2X7, and the subtypes of P2YRs expressed by microglia are metabotropic receptors P2Y<sub>2</sub>, P2Y<sub>6</sub>, P2Y<sub>12</sub>, and P2Y<sub>13</sub>. The adenosine P1 receptors expressed in microglia include A<sub>1</sub>R, A<sub>2A</sub>R, and A<sub>2B</sub>R. Among them, the activation of P2X4, P2X7, and adenosine A<sub>1</sub>, A<sub>2A</sub> receptors expressed in microglia can aggravate the pathological process of AD, whereas P2Y<sub>2</sub>, P2Y<sub>6</sub>, P2Y<sub>12</sub>, and P2Y<sub>13</sub> receptors expressed by microglia can induce neuroprotective effects. However, A<sub>1</sub>R activation also has a strong neuroprotective effect and has a significant anti-inflammatory effect in chronic neuroinflammation.

Pharmacological tools or adeno-associated viruses were administered at the acupoints to interfere with targeting signals. Protein expression was determined with qRT-PCR, WB, or immunofluorescent labeling. Cultured keratinocytes, HaCaT line, were subjected to hypotonic shock to simulate needling stimulation. Extracellular ATP and adenosine levels were quantified using luciferase-luciferin assay and ELISA, respectively. Acupuncture-induced prompt analgesia was impaired by inhibiting CD39 activities to prevent the degradation of ATP to AMP but was mimicked by using CD39 agonists. Acupuncture-induced ATP accumulation exhibited synchronous changes. Similarly, acupuncture analgesia was hindered by suppressing CD73 to prevent the conversion of AMP to adenosine. Furthermore, the acupuncture effect was replicated by agonism at P2Y2Rs but inhibited by antagonism at them. Acupuncture upregulated CD73 and P2Y2Rs but not CD39. Immunofluorescent labeling demonstrated that keratinocytes were a primary site for these proteins. Shallow acupuncture also demonstrated antinociception. In vitro tests showed that hypotonic shock induced HaCaT cells to release ATP and adenosine, which was impaired by suppressing CD39 and CD73, respectively. Finally, agonism at P2Y2Rs promoted ATP release and [Ca<sup>2+</sup>]<sub>i</sub> rise. CD39 at the acupoints contributes to the analgesic mechanism of acupuncture.
