They are activated and dysfunctional in brain disorders, such as Alzheimer's disease (AD) and depression. Platelets express the amyloid-precursor protein (APP) and release beta-amyloid40 into the blood. Recent evidence reports that platelets also express the microtubule-associated protein tau. In this study, we further characterized the molecular appearance of tau and examined its alterations in patients with neurocognitive impairment.\u0000\u0000\u0000METHODS\u0000Platelets were isolated from patients with AD, mild cognitive impairment (MCI) or depression and compared to healthy controls. Subsequently, FACS analysis was employed to characterize platelets for platelet surface P-selectin (CD62P). In order to enhance the detection levels, samples were pooled (15 samples per group) and analyzed by Lumipulse Assay, Western blots, and mass spectrometry.\u0000\u0000\u0000RESULTS\u0000Tau is expressed in human platelets and tau levels were decreased in platelets isolated from patients with AD and depression. Additionally, phospho-tau-181 was slightly increased in patients with depression. We show that tau is highly fragmented (20-40 kDa) in the platelet extracts using Western blot analysis. The mass spectrometry data did not show a clear identification of tau in the pooled platelet samples.\u0000\u0000\u0000CONCLUSIONS\u0000Our data reveal that tau is found in platelets, possibly in a highly fragmented form. Tau levels may be used as a potential diagnostic approach to differentiate AD and depression from healthy controls.","PeriodicalId":50430,"journal":{"name":"Frontiers in Bioscience-Landmark","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84112898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The species A. psidii is currently classified in the subfamily Aleyrodinae. This mitogenome is the first representative from the genus Aleuroclava.\u0000\u0000\u0000METHODS\u0000Next-generation sequencing was used to obtain the molecular data. We conducted phylogenetic analyses with 18 existing mitogenomes of whiteflies and three outgroups of psyllids, under the Maximum likelihood and Bayesian inference criteria.\u0000\u0000\u0000RESULTS\u0000The arrangement of genes differed between the mitogenome of A. psidii and the putative ancestral insect mitogenome, and also differed from the mitogenomes of other whiteflies. Mitochondrial gene rearrangements involved the transpositions of trnQ, trnY, and the protein-coding gene nad1. Most hemipteran mitogenomes have the same mitochondrial gene order as that inferred to be ancestral for insects. However, there are an increased number of gene rearrangements in the mitogenomes of whiteflies. Phylogenetic reconstructions supported Aleurodicinae and Aleyrodinae as being monophyletic.\u0000\u0000\u0000CONCLUSIONS\u0000Comparison of the gene order of mitogenomes revealed a clade-specific evolutionary trend in whiteflies.

Barriers to this approach included a lack of specificity towards cancer cells and intolerable toxicities. However, it was discovered that OVT increases cytokines such as interferon gamma and interleukins within the tumor microenvironment. This \"priming\" of the tumor microenvironment can lead to an improved innate immunologic response to tumor cells. An \"OVT-as-monotherapy\" approach has led to modest tumor response rates that have unfortunately not translated well in clinical trials. Currently, only one OVT agent-talimogene laherparevec (TVEC)-has been approved by the FDA for unresectable melanoma with limited visceral metastases. Further advancements in immunotherapy combined with improved viral engineering over the last decade have paved the way for a renewed focus on OVT. For example, various viruses have been modified to infiltrate and upregulate PD-L1 signaling within tumor cells. Upregulation of PD-L1 on tumor cells can increase tumor cell response to immunotherapies that utilize the interaction between PD-L1 on tumor cells and PD-1 on lymphocytes to allow for immune cell destruction of cancer cells. Combining OVT and immunotherapy offers more promise than OVT as monotherapy. Currently, several are actively investigating the combinatorial approach of OVT and immunotherapy in treating non-small cell lung cancer (NSCLC), colorectal cancer (CRC), breast cancer, melanoma, pancreatic cancer, multiple myeloma, and head and neck squamous cell carcinoma. In this review, we will discuss the history of OVT including its limitations as a monotherapy. We will also discuss the background of combining OVT and immunotherapy including possible benefits and pitfalls of this approach. Lastly, we will review current clinical trials investigating OVT and immunotherapy in multiple cancers.","PeriodicalId":50430,"journal":{"name":"Frontiers in Bioscience-Landmark","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85673840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To explore the role of the nsDSK II N-terminal extension (GGDDQ) in gut we delineated its structure-activity relationship (SAR) and identified novel agonists.

In spite of decades of intensive research, no cure for AD has been found yet. However, some treatments that may change disease progression and help control symptoms have been proposed. Beyond the classical hypotheses of AD etiopathogenesis, i.e., amyloid beta peptide (Aβ) accumulation and tau hyperphosphorylation, a trend in attributing a key role to other molecular mechanisms is prompting the study of different therapeutic targets. Hence, drugs designed to modulate inflammation, insulin resistance, synapses, neurogenesis, cardiovascular factors and dysbiosis are shaping a new horizon in AD treatment. Within this frame, an increase in the number of candidate drugs for disease modification treatments is expected, as well as a focus on potential combinatory multidrug strategies.The present review summarizes the latest advances in drugs targeting Aβ and tau as major contributors to AD pathophysiology.
