How Macrophages Deal with Death
REVIEWS CELL DEATH AND IMMUNITY How macrophages deal with death Greg Lemke Abstract | Tissue macrophages rapidly recognize and engulf apoptotic cells. These events require the display of so- called eat-me signals on the apoptotic cell surface, the most fundamental of which is phosphatidylserine (PtdSer). Externalization of this phospholipid is catalysed by scramblase enzymes, several of which are activated by caspase cleavage. PtdSer is detected both by macrophage receptors that bind to this phospholipid directly and by receptors that bind to a soluble bridging protein that is independently bound to PtdSer. Prominent among the latter receptors are the MER and AXL receptor tyrosine kinases. Eat-me signals also trigger macrophages to engulf virus- infected or metabolically traumatized, but still living, cells, and this ‘murder by phagocytosis’ may be a common phenomenon. Finally , the localized presentation of PtdSer and other eat- me signals on delimited cell surface domains may enable the phagocytic pruning of these ‘locally dead’ domains by macrophages, most notably by microglia of the central nervous system. In long- lived organisms, abundant cell types are often process. Efferocytosis is a remarkably efficient business: short- lived. In the human body, for example, the macrophages can engulf apoptotic cells in less than lifespan of many white blood cells — including neutro- 10 minutes, and it is therefore difficult experimentally to phils, eosinophils and platelets — is less than 2 weeks. detect free apoptotic cells in vivo, even in tissues where For normal healthy humans, a direct consequence of large numbers are generated7. Many of the molecules this turnover is the routine generation of more than that macrophages and other phagocytes use to recognize 100 billion dead cells each and every day of life1,2. -

Important Roles of C5a and C5ar in Tumor Development and Cancer Treatment
E3S Web o f Conferences 136, 06012 (2019) https://doi.org/10.1051/e3sconf/20191360 6012 ICBTE 2019 Important roles of C5a and C5aR in tumor development and cancer treatment Wang Yuxuan Bioengineering, School of Life Science, Anhui University,230601 Abstract: The complement system is part of the body's innate defense immune system, which can identify and eliminate invasive pathogenic microorganisms to maintain normal life activities. Complement Component 5a (C5a) is an active anaphylatoxin produced after complement system activation, closely related to tumor formation. C5a is highly expressed in a variety of tumors, and combines with its Complement Component 5a Receptor (C5aR) to increase the proliferation and migration of tumor cells. This review will comprehensively elaborate the important role of C5a/C5aR in the process of tumor genesis and development from the three aspects of signal transduction pathways related to tumor, C5a/C5aR and tumor formation, and C5a/C5aR inhibitors and tumor therapy. Finally, the principle of complement inhibition is used to inhibit tumor metastasis, reduce the rate of tumor diffusion, and control the trend of tumor deterioration. 1 Introduction The generation of tumor is closely related to the microenvironment in which tumor is located. A variety of cells in the microenvironment, such as lymphocytes, macrophages, fibroblasts and various molecules, such as complement and cytokines, are involved in the survival, proliferation and metastasis of tumor cells. Complement Component is a protein with enzyme activity. Since the discovery of complement system by Belgian doctor J. Bordet in 1890, a large number of studies have shown that complement exists in human serum, tissue fluid and cell membrane surface1. -

Investigation of Candidate Genes and Mechanisms Underlying Obesity
Prashanth et al. BMC Endocrine Disorders (2021) 21:80 https://doi.org/10.1186/s12902-021-00718-5 RESEARCH ARTICLE Open Access Investigation of candidate genes and mechanisms underlying obesity associated type 2 diabetes mellitus using bioinformatics analysis and screening of small drug molecules G. Prashanth1 , Basavaraj Vastrad2 , Anandkumar Tengli3 , Chanabasayya Vastrad4* and Iranna Kotturshetti5 Abstract Background: Obesity associated type 2 diabetes mellitus is a metabolic disorder ; however, the etiology of obesity associated type 2 diabetes mellitus remains largely unknown. There is an urgent need to further broaden the understanding of the molecular mechanism associated in obesity associated type 2 diabetes mellitus. Methods: To screen the differentially expressed genes (DEGs) that might play essential roles in obesity associated type 2 diabetes mellitus, the publicly available expression profiling by high throughput sequencing data (GSE143319) was downloaded and screened for DEGs. Then, Gene Ontology (GO) and REACTOME pathway enrichment analysis were performed. The protein - protein interaction network, miRNA - target genes regulatory network and TF-target gene regulatory network were constructed and analyzed for identification of hub and target genes. The hub genes were validated by receiver operating characteristic (ROC) curve analysis and RT- PCR analysis. Finally, a molecular docking study was performed on over expressed proteins to predict the target small drug molecules. Results: A total of 820 DEGs were identified between -

Age-related macular degeneration (AMD) is the most common cause of visual loss in developed countries, with a signifcant economic and social burden on public health. Although genome-wide and gene-candidate studies have been enabled to identify genetic variants in the complement system associated with AMD pathogenesis, the efect of gene-environment interaction is still under debate. In this review we provide an overview of the role of complement system and its genetic variants in AMD, summarizing the consequences of the interaction between genetic and environmental risk factors on AMD onset, progression, and therapeutic response. Finally, we discuss the perspectives of current evidence in the feld of genomics driven personalized medicine and public health. -
High-Throughput Proteomic Profiling of the Fish Liver Following Bacterial
Causey et al. BMC Genomics (2018) 19:719 https://doi.org/10.1186/s12864-018-5092-0 RESEARCH ARTICLE Open Access High-throughput proteomic profiling of the fish liver following bacterial infection Dwight R Causey1, Moritz A N Pohl1, David A Stead2, Samuel A M Martin1, Christopher J Secombes1 and Daniel J Macqueen1* Abstract Background: High-throughput proteomics was used to determine the role of the fish liver in defense responses to bacterial infection. This was done using a rainbow trout (Oncorhynchus mykiss) model following infection with Aeromonas salmonicida, the causative agent of furunculosis. The vertebrate liver has multifaceted functions in innate immunity, metabolism, and growth; we hypothesize this tissue serves a dual role in supporting host defense in parallel to metabolic adjustments that promote effectiveimmunefunction.Whilepaststudieshavereported mRNA responses to A. salmonicida in salmonids, the impact of bacterial infection on the liver proteome remains uncharacterized in fish. Results: Rainbow trout were injected with A. salmonicida or PBS (control) and liver extracted 48 h later for analysis on a hybrid quadrupole-Orbitrap mass spectrometer. A label-free method was used for protein abundance profiling, which revealed a strong innate immune response along with evidence to support parallel rewiring of metabolic and growth systems. 3076 proteins were initially identified against all proteins (n = 71,293 RefSeq proteins) annotated in a single high-quality rainbow trout reference genome, of which 2433 were maintained for analysis post-quality filtering. Among the 2433 proteins, 109 showed significant differential abundance following A. salmonicida challenge, including many upregulated complement system and acute phase response proteins, in addition to molecules with putative functions that may support metabolic re-adjustments. -
