Similarly, stimulation of microglia with the LXR agonist, GW3965, acts simultaneously to suppress inflammation and promote fibrillar Ab stimulated phagocytosis [47]. PubMed:21718217

On the other hand, they may show beneficial effects via facilitating aberrant protein clearance by means of microglial migration to the damaged, aberrant area, and phagocytosis of unnecessary materials in the early stages of AD PubMed:29626319
Microglial cells, the key immune cells of the brain, play an important part in the phagocytosis of Aβ PubMed:29626319
In addition, triggering receptor expressed on myeloid cells 2 (TREM2), ATP-binding cassette transporter A7, and CD33 also play key roles in microglial phagocytosis PubMed:29626319
A recent study has shown that ABCA7, mainly expressed in human microglial cells, also regulates microglial phagocytic function and decreases Aβ deposition (Zhao et al. 2015a) PubMed:29626319

In addition, Aβ1–42 can increase the expression of TREM2, a surface signaling receptor in microglia, and the up-regulation of TRME2 can facilitate microglial phagocytosis of Aβ1–42 PubMed:29626319
Phagocytosis and subsequent lysosomal damage trigger by Aβ initiate the activation of the NLRP3 inflammasome in the microglia (Halle et al., 2008) PubMed:24561250
For example, Beclin 1 suppression results in impaired microglial phagocytosis of Aβ and reduced recycling of TREM2 [108]. PubMed:29758300
In summary, these results indicate that heme from resuscitation with stored RBCs increases extracellular release of HMGB1, which inhibits macrophage phagocytosis of P. aeruginosa, leading to increased mortality. PubMed:29522519
By contrast, the parenchyma of the CNS is devoid of lymphatic vasculature2; in the brain, removal of cellular debris and toxic molecules, such as amyloid-β peptides, is mediated by a combination of transcellular transport mechanisms across the blood−brain and blood−cerebrospinal fluid (CSF) barriers7–9, phagocytosis and digestion by resident microglia and recruited monocytes and/or macrophages10,11, as well as CSF influx and ISF efflux through a paravascular (glymphatic) route12–14 PubMed:30046111
Intracellular Aβ clearance can be achieved through UPS and ALS, and extracellular Aβ is degraded by glial phagocytosis, such as microglia, astrocytes, and proteases from neurons and astrocytes (Fig. 2) PubMed:29626319
Microglial cells, the key immune cells of the brain, play an important part in the phagocytosis of Aβ PubMed:29626319
Aβ is cleared by receptor-mediated microglial phagocytosis and degradation, such as scavenger receptors, chemokine-like receptor 1, toll-like receptors, and G protein-coupled receptors including formyl peptide receptor 2 (Yu and Ye 2015) PubMed:29626319

There was direct evidence to show that microglial phagocytosis plays a pivotal role in clearance of tau in vitro and in vivo (Bolos et al. 2015) PubMed:29626319
Phagocytosis and subsequent lysosomal damage trigger by Aβ initiate the activation of the NLRP3 inflammasome in the microglia (Halle et al., 2008) PubMed:24561250
