Identification of phosphatases that dephosphorylate the co-chaperone BAG3.

Life Sci Alliance

February 2025

Institute of Biology III, Faculty of Biology, University of Freiburg, Freiburg im Breisgau, Germany

The co-chaperone BAG3 plays critical roles in maintaining cellular proteostasis. It associates with 14-3-3 proteins during the trafficking of aggregation-prone proteins and facilitates their degradation through chaperone-assisted selective autophagy in cooperation with small heat shock proteins. Although reversible phosphorylation regulates BAG3 function, the involved phosphatases remain unknown.

Stimulating cardiomyocyte (CM) dedifferentiation and cell cycle activity (DACCA) is essential for triggering daughter CM formation. In addition to transcriptional processes, RNA-binding proteins (RBPs) are emerging as crucial post-transcriptional players in regulating CM DACCA. However, whether post-transcriptional regulation of CM DACCA by RBPs could effectively trigger daughter CM formation remains unknown.

In Batesian mimicry, mimetic traits are not always as convincing as predicted by theory-in fact, inaccurate mimicry with only a superficial model resemblance is common and taxonomically widespread. The "selection trade-offs hypothesis" proposes a life-history trade-off between accurate mimetic traits and one or more vital biological functions. Here, using an accurate myrmecomorphic (ant-mimicking) jumping spider species, Myrmarachne smaragdina, we investigate how myrmecomorphic modifications to the body shape impact the internal anatomy in a way that could be functionally limiting.

Sensing, feeling and sentience in unicellular organisms and living cells.

Biosystems

January 2025

Department of Psychology, University of British Columbia, Vancouver, BC, Canada. Electronic address:

Cells represent the basic units of life, not only as structural building blocks, but also as cognitive agents endowed with subjective cellular feelings, sentience (consciousness), and cognitive infocomputatioal competence. Living cells act as 'Kantian Wholes': All of its parts exist for and by means of the whole system, allowing cells to use sentient agency for solving existential problems and evolve as living self-organizing units. Cell sentience is based on its excitable plasma membrane generating bioelectromagnetic fields that link to a whole-cell sensory architecture.

Trained innate immunity in response to nuclear antigens in systemic lupus erythematosus.

J Autoimmun

December 2024

Department of Nephrology, Radboud Research Institute for Medical Innovation, Radboud university medical center, Nijmegen, the Netherlands; Biomolecular Engineering and Imaging Institute, Icahn School of Medicine at Mount Sinai, New York, NY, USA. Electronic address:

Systemic lupus erythematosus (SLE) is an autoimmune disease directed against nuclear antigens, including those derived from apoptotic microparticles (MPs) and neutrophil extracellular traps (NETs). Here we investigated whether nuclear autoantigens can induce trained immunity in SLE patients. Trained immunity is a de facto innate immune memory elicited by an initial stimulus that induces a more vigorous long-term inflammatory response to subsequent stimuli.

Article Synopsis
  • Hippocampal sclerosis (HS) is a major cause of temporal lobe epilepsy (TLE) but can be hard to detect on MRI, leading to surgical delays, so researchers created open-source software to improve diagnosis.
  • The study involved 365 participants, using the software HippUnfold to analyze MRI scans and develop a logistic regression model that accurately identifies and localizes HS.
  • The classifier showed high accuracy in detecting HS in both initial and independent patient cohorts, proving effective for individual assessments by comparing patient data with normative growth patterns.

Several studies have demonstrated strong agreement between routine clinical visual assessment and quantification, suggesting that quantification approaches could support assessment by less experienced readers or in challenging cases. However, all studies to date have implemented a retrospective case collection, and challenging cases were generally underrepresented. We included all participants ( = 741) from the AMYPAD diagnostic and patient management study with available baseline amyloid PET quantification.

Neurobiological correlates of comorbidity in disorders across the affective disorders-psychosis spectrum.

J Psychiatr Res

Institute of Human Genetics, University of Bonn, School of Medicine & University Hospital Bonn, Bonn, Germany; Institute of Neuroscience and Medicine (INM-1), Research Centre Jülich, Jülich, Germany; Centre for Human Genetics, Philipps-University Marburg, Marburg, Germany. Electronic address:

Disorders across the affective disorders-psychosis spectrum such as major depressive disorder (MDD), bipolar disorder (BD), schizoaffective disorder (SCA), and schizophrenia (SCZ), have overlapping symptomatology and high comorbidity rates with other mental disorders. So far, however, it is largely unclear why some of the patients develop comorbidities. In particular, the specific genetic architecture of comorbidity and its relationship with brain structure remain poorly understood.

Mountains and Waves: Fontan Circulation in Different Environmental Conditions.

Pediatr Cardiol

November 2024

Department for Pediatric Cardiology, University of Leipzig - Heart Center, Strümpellstr. 39, 04289, Leipzig, Germany.

As surgical options and medical care for patients with univentricular heart physiology continue to improve, leading to increased life expectancy and quality of life, a new population of Fontan patients is growing up with the desire to participate in leisure activities, including aquatic activities, high-altitude stays, and air travel. Due to significant data gaps and insufficient experience, current guidelines do not provide clear recommendations, leading to uncertainty and sometimes restrictive patient management. This review summarizes new insights and the current state of research on this subject and provides an overview of the long overdue change in policies toward less restrictive counseling for Fontan patients regarding swimming, diving, high-altitude stays, and air travel.

Prophylaxis is the standard of care for patients with severe hemophilia, patients with moderate hemophilia, or those with another congenital bleeding disorder that is associated with a severe bleeding phenotype and/or a high risk of spontaneous life-threatening bleeding. Patients with nonsevere hemophilia (factor VIII [FVIII] ≥ 1%) may also have a bleeding phenotype that requires prophylaxis. To date, however, there are no clear criteria as to when prophylaxis is indicated in these patients.

Trained immunity induces antigen-agnostic enhancement of host defense and protection against secondary infections, but inappropriate activation can contribute to the pathophysiology of inflammatory diseases. Tight regulation of trained immunity is therefore needed to avoid pathology, but little is known about the endogenous processes that modulate it. Here, we investigated the potential of IL-10, a prototypical anti-inflammatory cytokine, to inhibit trained immunity.
