The Complement System of Agnathans

Frontiers in Immunology, 2018
Agnathans (lamprey and hagfish) are a group of primitive jawless fish. Jawed vertebrates possess adaptive immunity including immunoglobulins, while agnathans lack immunoglobulins but have alternative adaptive immunity in which variable lymphocyte ...

Isolation and characterization of novel primary cells from the human distal outflow pathway

Scientific Reports, 2021
Ocular hypertension occurs due to increased resistance to aqueous humor removal through the conventional outflow pathway. Unlike the proximal region of the conventional outflow pathway, the distal region has not been well studied, mostly due to lack of ...

The complement lectin pathway after cardiac arrest [PDF]

Scandinavian Journal of Immunology, 2018
AbstractThe lectin pathway (LP) of the complement system may initiate inflammatory reactions when body tissue is altered. We aimed to investigate the levels of the LP proteins in out‐of‐hospital cardiac arrest patients, and to compare these with healthy individuals.

AIF1+CSF1R+ MSCs, induced by TNF‐α, act to generate an inflammatory microenvironment and promote hepatocarcinogenesis

Hepatology, EarlyView., 2022
Mesenchymal stem cells subset, educated by TNF‐α, are involved to generate inflammatory microenvironment and promote hepatocarcinogenesis Abstract Background and Aims Increasing evidence suggests that mesenchymal stem cells (MSCs) home to injured local tissues and the tumor microenvironment in the liver.

Ecotin, a microbial inhibitor of serine proteases, blocks multiple complement dependent and independent microbicidal activities of human serum.

PLoS Pathogens, 2019
Ecotin is a serine protease inhibitor produced by hundreds of microbial species, including pathogens. Here we show, that ecotin orthologs from Escherichia coli, Yersinia pestis, Pseudomonas aeruginosa and Leishmania major are potent inhibitors of MASP-1 ...

Emergence of highly profibrotic and proinflammatory Lrat+Fbln2+ HSC subpopulation in alcoholic hepatitis

Hepatology, EarlyView., 2022
Lrat+ quiescent hepatic stellate cells (qHSC) give rise to Lrat+Fbln2+ activated HSC (aHSC) in alcohol‐associated hepatitis and this subpopulation is highly profibrotic, inflammatory, and immunoregulatory based on their single cell transcriptomic profile. Abstract Background and Aims Relative roles of HSCs and portal fibroblasts in alcoholic hepatitis (

Research advances on plant lectin receptor-like kinases in abiotic stress response

Guangxi Zhiwu, 2023
Plants are exposed to various stress during their growth and development, and abiotic stress is one of the most significant factors. Receptor-like kinases (RLKs) are widely present in plants that can quickly and effectively respond to stress, ultimately ...

MASP-1 and MASP-3 Bind Directly to Aspergillus fumigatus and Promote Complement Activation and Phagocytosis

Journal of Innate Immunity, 2021
Activation of the complement system is mediated by the interaction between pathogens and pattern recognition molecules (PRMs); mannose-binding lectin (MBL), ficolins, and collectin-10/-11 from the lectin pathway and C1q from the classical pathway. Lectin

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Role of the lectin complement pathway in kidney transplantation [PDF]

Immunobiology, 2016
In the last 15 years two major advances in the role of complement in the kidney transplant have come about. The first is that ischaemia reperfusion injury and its profound effect on transplant outcome is dependent on the terminal product of complement activation, C5b-9. The second key observation relates to the function of the small biologically active
