APOE in the bullseye of neurodegenerative diseases: impact of the APOE genotype in Alzheimer’s disease pathology and brain diseases. Mol Neurodegener 2022; 17:62.

Abstract
ApoE is the major lipid and cholesterol carrier in the CNS. There are three major human polymorphisms, apoE2, apoE3, and apoE4, and the genetic expression of APOE4 is one of the most influential risk factors for the development of late-onset Alzheimer's disease (AD). Neuroinflammation has become the third hallmark of AD, together with Amyloid-β plaques and neurofibrillary tangles of hyperphosphorylated aggregated tau protein. This review aims to broadly and extensively describe the differential aspects concerning apoE. Starting from the evolution of apoE to how APOE's single-nucleotide polymorphisms affect its structure, function, and involvement during health and disease. This review reflects on how APOE's polymorphisms impact critical aspects of AD pathology, such as the neuroinflammatory response, particularly the effect of APOE on astrocytic and microglial function and microglial dynamics, synaptic function, amyloid-β load, tau pathology, autophagy, and cell–cell communication. We discuss influential factors affecting AD pathology combined with the APOE genotype, such as sex, age, diet, physical exercise, current therapies and clinical trials in the AD field. The impact of the APOE genotype in other neurodegenerative diseases characterized by overt inflammation, e.g., alpha- synucleinopathies and Parkinson's disease, traumatic brain injury, stroke, amyotrophic lateral sclerosis, and multiple sclerosis, is also addressed. Therefore, this review gathers the most relevant findings related to the APOE genotype up to date and its implications on AD and CNS pathologies to provide a deeper understanding of the knowledge in the APOE field.

Abstract
Background Various apolipoproteins widely distributed among vertebrata play key roles in lipid metabolism and have a direct correlation with human diseases as diagnostic markers. However, the evolutionary progress of apolipoproteins in species remains unclear. Nine human apolipoproteins and well-annotated genome data of 30 species were used to identify 210 apolipoprotein family members distributed among species from fish to humans. Our study focused on the evolution of nine exchangeable apolipoproteins (ApoA-I/II/IV/V, ApoC-I~IV and ApoE) from Chondrichthyes, Holostei, Teleostei, Amphibia, Sauria (including Aves), Prototheria, Marsupialia and Eutheria. Results In this study, we reported the overall distribution and the frequent gain and loss evolutionary events of apolipoprotein family members in vertebrata. Phylogenetic trees of orthologous apolipoproteins indicated evident divergence between species evolution and apolipoprotein phylogeny. Successive gain and loss events were found by evaluating the presence and absence of apolipoproteins in the context of species evolution. For example, only ApoA-I and ApoA-IV occurred in cartilaginous fish as ancient apolipoproteins. ApoA-II, ApoE, and ApoC-I/ApoC-II were found in Holostei, Coelacanthiformes, and Teleostei, respectively, but the latter three apolipoproteins were absent from Aves. ApoC-I was also absent from Cetartiodactyla. The apolipoprotein ApoC-III emerged in terrestrial animals, and ApoC-IV first arose in Eutheria. The results indicate that the order of the emergence of apolipoproteins is most likely ApoA-I/ApoA-IV, ApoE, ApoA-II, ApoC-I/ApoC-II, ApoA-V, ApoC-III, and ApoC-IV. Conclusions This study reveals not only the phylogeny of apolipoprotein family members in species from Chondrichthyes to Eutheria but also the occurrence and origin of new apolipoproteins. The broad perspective of gain and loss events and the evolutionary scenario of apolipoproteins across vertebrata provide a significant reference for the research of apolipoprotein function and related diseases.

Abstract
Apolipoprotein E (apo E) is a human glycoprotein with 299 amino acids, and it is a
major component of very low density lipoproteins (VLDL) and a group of high-density
lipoproteins (HDL). Phylogenetic studies are important to clarify how various apo E
proteins are related in groups of organisms and whether they evolved from a common
ancestor. Here, we aimed at performing a phylogenetic study on apo E carrying
organisms. We employed a classical and robust method, such as Maximum Likelihood
(ML), and compared the results using a more recent approach based on complex
networks. Thirty-two apo E amino acid sequences were downloaded from NCBI. A clear
separation could be observed among three major groups: mammals, fish and amphibians.
The results obtained from ML method, as well as from the constructed networks showed
two different groups: one with mammals only (C1) and another with fish (C2), and a
single node with the single sequence available for an amphibian. The accordance in
results from the different methods shows that the complex networks approach is
effective in phylogenetic studies. Furthermore, our results revealed the conservation
of apo E among animal groups.

Abstract
Cestodes are unable to synthesize de novo most of their own membrane lipids, including cholesterol, and have to take them up from the host during an infection. The underlying molecular mechanisms are so far unknown. Here we report the identification and characterization of a novel gene, Emabp, which is expressed by larval stages and adults of the fox tapeworm Echinococcus multilocularis. The encoded protein, EmABP, displays significant homologies to apolipoprotein A-I binding protein (AI-BP) of mammalian origin and to metazoan YjeF_N domain proteins. Like mammalian AI-BP, EmABP carries an export-directing signal sequence which is absent in predicted AI-BP orthologs from the related flatworms Schistosoma japonicum and Schmidtea mediterranea. Using a specific antibody and immunoprecipitation techniques, we demonstrate that EmABP is secreted into the extraparasitic environment and into the hydatid fluid of in vitro-cultivated metacestode vesicles. Furthermore, we show that apolipoprotein A-I (apoA-I), a major constituent of cholesterol-transporting high-density lipoproteins, is present in hydatid fluid. By pulldown experiments, we demonstrate that recombinantly expressed, purified EmABP interacts with purified human apoA-I and is able to precipitate apoA-I from human serum. On the basis of these features and the suggested function of AI-BP in cholesterol transport in higher eukaryotes, we propose a role for EmABP in cholesterol and lipid uptake mechanisms of larval E. multilocularis.

Association of apolipoprotein E polymorphisms in patients with non-alcoholic steatohepatitis. Dig Dis Sci 2008; 53:3218-24.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is the most common cause of abnormal hepatic steatosis in the absence of alcohol abuse worldwide. Non-alcoholic steatohepatitis (NASH) is the most progressive form of NAFLD. The aim of this study was to investigate the role of apolipoprotein E (APOE) polymorphisms in the development of NASH. We analysed 57 NASH patients and 245 healthy controls using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in a case-control study. The diagnosis of the patients was based on liver biopsy. The serum levels of glucose, lipids, vitamin B12, folic acid, homocysteine, insulin, total biluribin, total protein, albumin, ferritin, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were determined in all of the subjects. Body mass index (BMI), waist circumference (WC), AST, ALT, fasting blood sugar (FBS), total cholesterol, triglyceride (TG), low-density lipoprotein (LDL) cholesterol, very low-density lipoprotein (VLDL) cholesterol, insulin and ferritin levels were significantly higher in the 57 patients with NASH compared with the 245 healthy controls. The APOE epsilon3 allele was overrepresented in the whole group of NASH patients (epsilon3=97.37% in NASH versus 82.45% in controls). The APOE polymorphism was statistically significantly associated with NASH (chi(2)=15.741; p=0.008). The APOE3/3 genotype (odds ratio [OR]=7.941; p=0.000) was strongly associated with increased risk for NASH in all NASH patients. Consequently, the APOE3/3 genotype may play a role in the aetiopathogenesis of NASH.
