SARS-CoV-2 enhances complement-mediated endothelial injury via the suppression of membrane complement regulatory proteins

Emerging Microbes and Infections
Complement hyperactivation and thrombotic microangiopathy are closely associated with severe COVID-19. Endothelial dysfunction is a key mechanism underlying thrombotic microangiopathy.

Complement factor H binding by different Lyme disease and relapsing fever Borrelia in animals and human

BMC Research Notes, 2009
Background Borreliae employ multiple immune evasive strategies such as binding to complement regulatory proteins [factor H (fH) and factor H like-1 (FHL1)], differential regulation of surface membrane proteins, antigenic variation, and binding of ...

Peripheral blood proteome biomarkers distinguish immunosuppressive features of cancer progression

Molecular Oncology, EarlyView.
Immune status significantly influences cancer progression. This study used plasma proteomics to analyze benign 67NR and malignant 4T1 breast tumor models at early and late tumor stages. Immune‐related proteins–osteopontin (Spp1), lactotransferrin (Ltf), calreticulin (Calr) and peroxiredoxin 2 (Prdx2)–were associated with systemic myeloid‐derived ...

Evasion Mechanisms Used by Pathogens to Escape the Lectin Complement Pathway

Frontiers in Microbiology, 2017
The complement system is a crucial defensive network that protects the host against invading pathogens. It is part of the innate immune system and can be initiated via three pathways: the lectin, classical and alternative activation pathway.

CircCCNB1 inhibits vasculogenic mimicry by sequestering NF90 to promote miR‐15b‐5p and miR‐7‐1‐3p processing in nasopharyngeal carcinoma

Molecular Oncology, EarlyView.
CircCCNB1 expression is down‐regulated in nasopharyngeal carcinoma (NPC); thus, less NF90 protein is bound to circCCNB1 and more binds to pri‐miRNAs, blocking their (pri‐miRNAs) binding to DGCR8 and inhibiting the processing and generation of miR‐15b‐5p/miR‐7‐1‐3p. Furthermore, decreased miR‐15b‐5p/miR‐7‐1‐3p promotes the expression of the target genes

Expression of the membrane complement regulatory proteins (CD55 and CD59) in human thymus.

Folia Histochemica et Cytobiologica, 2007
CD59 is one of the key molecules involved in cell protection against autologus complement. The fact that complement regulatory proteins are able to prevent hyperacute rejection of organs in pig to primate model, raises the question of possible complement

Immune Evasion Strategies of Relapsing Fever Spirochetes

Frontiers in Immunology, 2020
Relapsing fever (RF) is claimed a neglected arthropod-borne disease caused by a number of diverse human pathogenic Borrelia (B.) species. These RF borreliae are separated into the groups of tick-transmitted species including B. duttonii, B.

The Role of Membrane Complement Regulatory Proteins in Cancer Immunotherapy

, 2008
Anti-tumor monoclonal antibody therapy represents one of the earliest targeted therapies in clinical cancer care and has achieved great clinical promise. Complement activation mediated by anti-tumor mAbs can result in direct tumor lysis or enhancement of antibody-dependent cellular cytotoxicy.

Immunohistochemical localization of complement regulatory proteins in the human retina.

Histology and histopathology, 2012
Age-related macular degeneration (AMD) is a complex disease. Genetic studies have found strong associations between AMD and variants of several complement pathway-associated genes. The regulation of the complement cascade seems to be critical in the pathogenesis of AMD. In 45 human donor eyes immunohistochemistry was performed using antibodies directed

Classification of acute myeloid leukemia based on multi‐omics and prognosis prediction value

Molecular Oncology, EarlyView.
The Unsupervised AML Multi‐Omics Classification System (UAMOCS) integrates genomic, methylation, and transcriptomic data to categorize AML patients into three subtypes (UAMOCS1‐3). This classification reveals clinical relevance, highlighting immune and chromosomal characteristics, prognosis, and therapeutic vulnerabilities.
