September 2024 – The European Research Council awarded an ERC Starting Grant to Anna-Sophia Wahl for studying fundamental principles of neuronal repair after stroke. With her team Anna-Sophia will examine how individual neurons in the active brain react to microstrokes and how the survival and rewiring of neurons can be enhanced to prevent cognitive decline after stroke. >>

August 2024 –  Using a novel experimental model, ISD researchers showed that stroke activates the AIM2 inflammasome in atherosclerotic plaques via increased circulating cell-free DNA, causing inflammation, plaque destabilization, and recurrent stroke. Neutrophil NETosis was identified as the main source of cell-free DNA. Neutralizing cell-free DNA or inhibiting inflammasome activation reduced stroke recurrence, offering new perspectives for the prevention of early recurrent events >>

July 2024 – ISD researchers hypothesized in a newly published study that the high rate of comorbidities that develop after a stroke could have a common immunological cause. A Myeloid innate immune memory was identified as causing remote organ dysfunction post-stroke. Single-cell sequencing revealed persistent pro-inflammatory changes in monocytes/macrophages up to 3 months after brain injury, especially in the heart, causing cardiac fibrosis and dysfunction. Neutralizing IL-1β or blocking monocyte trafficking prevented post-stroke cardiac dysfunction, suggesting immune-targeted therapies for secondary prevention. >>

July 2024 – Rare mutations in HTRA1 cause cerebral vasculopathy and stroke. Using in vitro, in silico and in vivo analyses, the Dichgans lab in collaboration with colleagues from Duisburg established mechanistically distinct protein repair approaches to reverse the deleterious effects of pathogenic mutations interfering with the oligomeric assembly and protease function of HTRA1. Their findings exemplify the feasibility of rational strategies to correct protein conformations and open perspectives for precision medicine >>

The second day featured an overview of research highlights presented through a series of presentations and poster sessions led by Postdoctoral Fellows and PhD students.

May 2024 – Combining genetic analyses in large international biobanks with experimental studies on human cells, ISD investigators found that rare HTRA1 variants affect vascular risk via a loss of enzymatic function of the HTRA1 protease, whereas a common causal variant independently affects vascular risk by influencing the circulating HTRA1 mRNA and protein levels. They further uncovered a complex relationship with other diseases including migraine and macular dystrophy. >>

April 2024 – The ISD is organising this year's International Stroke Genetics Consortium (ISGC) workshop, held on LMU campus at the St.-Vinzenz-Haus of LMU Hospital close to the city center from April 24 to April 26, 2024.

March 2024 – A proteomic profiling study on brain endothelial cells (BEC) by ISD investigators reveals a dysregulation of key regulators of endocytosis and receptor recycling (most prominently Arf6), macropinocytosis, and lysosomal degradation during aging. The study identified changes undetected in transcriptomic studies such as an accumulation of vesicle cargo and receptor ligands including Apoe. | Data are accessible via an interactive database https://becaging.de/

February 2024 – Integrating genetic information from >520,000 individuals with data from plasma proteomics, the team of Marios Georgakis identified a proteomic signature of IL-6 signaling activation and mediators of its effects on cardiovascular disease. Their analyses suggest, that the interferon-γ-inducible chemokine CXCL10 is a potentially causal mediator for atherosclerosis in different vascular beds (coronary, cerebral, and peripheral arteries) and could serve as a promising drug target for atheroprotection. >>

January 2024 – A combined neuroimaging and biofluid biomarker study investigated whether synaptic changes are associated with accelerated tau spreading in Alzheimer’s disease (AD). Higher levels of the presynaptic protein GAP-43 speed up the spread of tau in AD. These findings by Nico Franzmeier (ISD) and others are relevant for developing treatments to slow down the progression of the disease. >>

December 2023 – A study by Josh Shrouder within the Plesnila lab, together with collaborators reveals how dysfunction of capillary pericytes aggravates no-reflow after ischemic stroke. These longitudinal in vivo results challenge the notion that pericytes are terminally susceptible to ischemia, and demonstrate how acute interventions targeting pericyte constriction could be harnessed to accelerate the restoration of capillary blood flow and improve stroke outcome. >>

November 2023 – A study by the BernhagenLab and collaborators shows that specific plant proteins resemble human signaling proteins of the immune system and can bind to their receptors. While representing basic cross-discipline research, the work might have translational implications, as the receptors are drivers of cardiovascular diseases and inflammation.>>

November 2023 – A study by Anna Steward and Nicolai Franzmeier reveals that ApoE4 carriers experience faster and earlier disease progression due to amyloid's impact on tau. These results urge earlier intervention for ApoE4 carriers who show reduced efficacy in response to anti-amyloid drugs. This insight, crucial for 40-60% of sporadic AD cases, suggests a potential shift in therapy approaches, advocating for tailored clinical studies to validate this new paradigm. >>

October 2023 – Main results from TREAT-SVDs, an EU funded multicenter, open-label, randomised, crossover trial were presented at the European Stroke Organisation Conference (ESOC) in Munich and recently published in the Lancet Neurolgy. The results show that four weeks of treatment with amlodipine, losartan, or atenolol did not differ in their effects on cerebrovascular reactivity in people with sporadic small vessel disease but did result in differential treatment effects in patients with CADASIL. >>

August 2023 – Neuroimmune interactions exhibit remarkable complexity, and exploring brain borders has gained significant attention in the quest for innovative approaches to diagnose, monitor, and treat brain pathologies. The recent discovery of connections between the skull and meninges has brought the skull into focus. A large collaborative research team led by the Erturk lab extensively examined the molecular and structural aspects of the skull in both mice and humans. Their findings demonstrated that skull inflammation can serve as an indicator of brain inflammation in patients suffering from diverse neurological disorders. >>
