Stress-Induced Enhanced Long-Term Potentiation and Reduced Threshold for N-Methyl-D-Aspartate Receptor- and beta-Adrenergic Receptor-Mediated Synaptic Plasticity in Rodent Ventral Subiculum.
Bartsch JC, von Cramon M, Gruber D, Heinemann U, Behr J. Bartsch JC, et al. Among authors: heinemann u. Front Mol Neurosci. 2021 Apr 22;14:658465. doi: 10.3389/fnmol.2021.658465. eCollection 2021. Front Mol Neurosci. 2021. PMID: 33967694 Free PMC article.
Therefore, we investigated the impact of a single exposure to an inherently stressful two-way active avoidance conditioning on the induction of long-term potentiation (LTP) at CA1-subiculum synapses in ventral hippocampal slices from young adult rats 1 day after stressor e …

Persistent increase in ventral hippocampal long-term potentiation by juvenile stress: A role for astrocytic glutamine synthetase.
Ivens S, Çalışkan G, Papageorgiou I, Cesetti T, Malich A, Kann O, Heinemann U, Stork O, Albrecht A. Ivens S, et al. Among authors: heinemann u. Glia. 2019 Dec;67(12):2279-2293. doi: 10.1002/glia.23683. Epub 2019 Jul 17. Glia. 2019. PMID: 31313857
We describe that such juvenile stress in rats, regardless of additional stress in adulthood, leads to reduced synaptic efficacy in the ventral CA1 (vCA1) Schaffer collaterals, but increased long-term potentiation (LTP) of synaptic transmission after high-frequency stimulat …

TGFβ signaling is associated with changes in inflammatory gene expression and perineuronal net degradation around inhibitory neurons following various neurological insults.
Kim SY, Senatorov VV Jr, Morrissey CS, Lippmann K, Vazquez O, Milikovsky DZ, Gu F, Parada I, Prince DA, Becker AJ, Heinemann U, Friedman A, Kaufer D. Kim SY, et al. Among authors: heinemann u. Sci Rep. 2017 Aug 9;7(1):7711. doi: 10.1038/s41598-017-07394-3. Sci Rep. 2017. PMID: 28794441 Free PMC article.
Brain damage due to stroke or traumatic brain injury (TBI), both leading causes of serious long-term disability, often leads to the development of epilepsy. Patients who develop post-injury epilepsy tend to have poor functional outcomes. ...

Epileptiform activity and spreading depolarization in the blood-brain barrier-disrupted peri-infarct hippocampus are associated with impaired GABAergic inhibition and synaptic plasticity.
Lippmann K, Kamintsky L, Kim SY, Lublinsky S, Prager O, Nichtweiss JF, Salar S, Kaufer D, Heinemann U, Friedman A. Lippmann K, et al. Among authors: heinemann u. J Cereb Blood Flow Metab. 2017 May;37(5):1803-1819. doi: 10.1177/0271678X16652631. Epub 2016 Jan 1. J Cereb Blood Flow Metab. 2017. PMID: 27252228 Free PMC article.
Slices generating epileptiform activity at seven days revealed impaired bidirectional long-term plasticity following high and low-frequency stimulation protocols. ...

Synaptic plasticity in area CA1 of rat hippocampal slices following intraventricular application of albumin.
Salar S, Lapilover E, Müller J, Hollnagel JO, Lippmann K, Friedman A, Heinemann U. Salar S, et al. Among authors: heinemann u. Neurobiol Dis. 2016 Jul;91:155-65. doi: 10.1016/j.nbd.2016.03.008. Epub 2016 Mar 10. Neurobiol Dis. 2016. PMID: 26972679
We demonstrate alterations in both homo- and heterosynaptic plasticity compared to control conditions in ex vivo slice studies. Albumin-treated tissue reveals (1) reduced long-term depression following low-frequency stimulation; (2) increased long-term potentiation …

Shifts in excitatory/inhibitory balance by juvenile stress: A role for neuron-astrocyte interaction in the dentate gyrus.
Albrecht A, Ivens S, Papageorgiou IE, Çalışkan G, Saiepour N, Brück W, Richter-Levin G, Heinemann U, Stork O. Albrecht A, et al. Among authors: heinemann u. Glia. 2016 Jun;64(6):911-22. doi: 10.1002/glia.22970. Epub 2016 Feb 15. Glia. 2016. PMID: 26875694
Indeed, we observed increased inhibition and a lack of facilitation in response to paired-pulse stimulation at short interstimulus intervals in the dorsal DG after JS, while no alterations were evident in basal synaptic transmission or forms of long-term plasticity. The sh …

Long-term changes in the CA3 associative network of fear-conditioned mice.

The CA3 associative network plays a critical role in the generation of network activity patterns related to emotional state and fear memory. We investigated long-term changes in the corticosterone (CORT)-sensitive function of this network following fear conditioning and fe …
