Urokinase plasminogen activator and plasmin contribute to detach neoplastic cells from solid tumor and facilitate the movement of these cells through interstitium and capillary walls as well as infiltration of the surrounding structures. Plasminogen activators inhibitors fulfill a regulatory function in these processes. Determining activity and concentration, finding subcellular, cellular and zonal localization of every component of plasminogen activation system has diagnostic and prognostic importance in different lung cancer types.

The interaction of tPA with NMDAR1 drives neuroinflammation and neurodegeneration in α-synuclein-mediated neurotoxicity.
J Neuroinflammation
January 2025
Department of Molecular and Integrative Physiology, University of Michigan Medical School, Ann Arbor, MI, USA.
The thrombolytic protease tissue plasminogen activator (tPA) is expressed in the CNS, where it regulates diverse functions including neuronal plasticity, neuroinflammation, and blood-brain-barrier integrity. However, its role in different brain regions such as the substantia nigra (SN) is largely unexplored. In this study, we characterize tPA expression, activity, and localization in the SN using a combination of retrograde tracing and β-galactosidase tPA reporter mice.

Tenecteplase for the Treatment of Pediatric Arterial Ischemic Stroke: A Safety Surveillance Report.
Neurology
February 2025
Department of Neurology, Washington University School of Medicine, St. Louis, MO.
Objectives: Intravenous tenecteplase (TNK) is increasingly used to treat adult patients with acute arterial ischemic stroke, but the risk profile of TNK in childhood stroke is unknown. This study aims to prospectively gather safety data regarding TNK administration in children.
Methods: Since December 2023, a monthly email survey was sent to participants recruited from the International Pediatric Stroke Study and Pediatric Neurocritical Care Research Group querying recent experience with TNK in childhood stroke.
Safe Implementation of Treatments in Stroke: a study on intravenous thrombolysis in patients over 80 years of age with acute ischaemic stroke.
BMJ Open
January 2025
Department of Neurology, Karolinska University Hospital, Stockholm, Sweden.
Objectives: To investigate the safety and efficacy outcomes of intravenous thrombolysis (IVT) in patients aged >80 years with acute ischaemic stroke (AIS) after IVT was approved in this patient population in several European and non-European countries during 2018-2019.
Design: This is an observational registry study using prospectively collected data from the Safe Implementation of Treatment in Stroke (SITS) registry. Comparisons will be performed between patients treated post-approval (July 2018 to December 2021) period with those treated pre-approval (June 2015 to June 2018) period using propensity score matching (PSM).

To evaluate the safety and efficacy of dual antiplatelet therapy (DAPT) versus tenecteplase in minor non-disabling acute ischemic stroke. This retrospective observational study utilized data from our stroke database. All consecutive patients with minor non-disabling acute ischemic stroke treated with either DAPT or tenecteplase between January 2020 and June 2023 were included in the analysis.
