Alveolar Macrophage Plasminogen Activator

open access: yesExperimental Lung Research, 1984
Plasminogen activator is a neutral serine protease secreted by many different cells, including activated peritoneal macrophages, which can mediate both inflammation and fibrinolysis and perhaps cytolysis of tumor cells. Secretion of plasminogen activator by rabbit alveolar macrophages derived from normal animals and rabbits pretreated with bacillus ...

HYALURONIDASE ACTIVITY OF ALVEOLAR MACROPHAGES [PDF]

open access: yesJournal of Histochemistry & Cytochemistry, 1968
Hyaluronidase activity was detected in preparations of isolated rabbit lung alveolar macrophages. The enzyme manifested a pH optimum of 3.9 with no activity detected above pH 5. Analysis of reaction products isolated from digests containing low enzyme concentrations revealed the production of large oligosaccharides from hyaluronic acid without the ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Brief Glutamine Pretreatment Increases Alveolar Macrophage CD163/Heme Oxygenase-1/p38-MAPK Dephosphorylation Pathway and Decreases Capillary Damage but Not Neutrophil Recruitment in IL-1/LPS-Insufflated Rats. [PDF]

open access: yesPLoS ONE, 2015
Glutamine (GLN) attenuates acute lung injury (ALI) but its effect on alveolar macrophages is unknown. We hypothesized that GLN pretreatment would induce the anti-inflammatory CD163/heme oxygenase (HO)-1/p38-MAPK dephosphorylation pathway in alveolar ...

Increased levels of hyaluronic acid in bronchoalveolar lavage from patients with interstitial lung diseases, relationship with lung function and inflammatory cells recruitment [PDF]

open access: yes, 2014
Purpose: Interstitial Lung Diseases (ILD) are characterized by inflammation and fibrosis. It described the role of hyaluronic acid (HA) as an immune-regulator. It is not known if HA contributes to the recruitment of inflammatory cells associated with ILD.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Inhaled Interleukin-10 before and after induction of experimental endotoxemia in the rat : effects on the inflammatory response [PDF]

open access: yes, 2007
To determine the effects of inhaled IL-10 at different doses and different time points on the pulmonary and systemic inflammatory response during endotoxemia, 48 ventilated, anaesthetized rats (mean body weight ± standard deviation, 500 ± 33g) were ...

Macrophage TNF-α mediates parathion-induced airway hyperreactivity in guinea pigs. [PDF]

open access: yes, 2013
Organophosphorus pesticides (OPs) are implicated in human asthma. We previously demonstrated that, at concentrations that do not inhibit acetylcholinesterase activity, the OP parathion causes airway hyperreactivity in guinea pigs as a result of ...

PPARs in Alveolar Macrophage Biology [PDF]

open access: yesPPAR Research, 2007
PPARs, most notably PPAR-γ, play a crucial role in regulating the activation of alveolar macrophages, which in turn occupy a pivotal place in the immune response to pathogens and particulates drawn in with inspired air. In this review, we describe the dual role of the alveolar macrophage as both a first-line defender through its phagocytotic activity ...

Development of human monoclonal antibodies against TARM1 by yeast display

open access: yesFEBS Open Bio, EarlyView.
Human monoclonal antibodies against TARM1 are generated by yeast display‐guided selection. These antibodies bind to soluble and cell‐surface forms of TARM1. Also, these antibodies exhibit agonistic activity in the NFAT‐GFP reporter assay, indicating that TARM1 signaling can be functionally modulated by antibodies and suggesting TARM1 as a potential ...
