12 p, 2.4 MB A coordinated response at the transcriptome and interactome level is required to ensure uropathogenic escherichia coli survival during bacteremia / Sánchez de Groot, Natalia (Centre de Regulació Genòmica) ; Torrent Burgas, Marc (Universitat Autònoma de Barcelona. Departament de Bioquímica i de Biologia Molecular)
Localized infections or disruption of the skin barrier can enable the entry of bacteria into the bloodstream, possibly leading to acute inflammation and sepsis. There is currently no holistic view on how bacteria can survive and spread in the bloodstream. [...]

Amyloids consist of repetitions of a specific polypeptide chain in a regular cross-β-sheet conformation. Amyloid propensity is largely determined by the protein sequence, the aggregation process being nucleated by specific and short segments. [...]

13 p, 1.1 MB Protein aggregation into insoluble deposits protects from oxidative stress / Carija, Anita (Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí") ; Navarro, Susanna (Universitat Autònoma de Barcelona. Departament de Bioquímica i Biomedicina Molecular) ; Sánchez de Groot, Natalia (Centre de Regulació Genòmica) ; Ventura, Salvador (Institut de Biotecnologia i de Biomedicina "Vicent Villar Palasí")
Protein misfolding and aggregation have been associated with the onset of neurodegenerative disorders. Recent studies demonstrate that the aggregation process can result in a high diversity of protein conformational states, however the identity of the specific species responsible for the cellular damage is still unclear. [...]

6 p, 5.8 MB Centrality in the host-pathogen interactome is associated with pathogen fitness during infection / Crua Asensio, Núria (Hospital Universitari Vall d'Hebron) ; Muñoz Giner, Elisabet (Hospital Universitari Vall d'Hebron) ; Sánchez de Groot, Natalia (Universitat Pompeu Fabra) ; Torrent Burgas, Marc (Universitat Autònoma de Barcelona. Departament de Bioquímica i Biologia Molecular)
To perform their functions proteins must interact with each other, but how these interactions influence bacterial infection remains elusive. Here we demonstrate that connectivity in the host-pathogen interactome is directly related to pathogen fitness during infection. [...]

11 p, 2.0 MB Is membrane homeostasis the missing link between inflammation and neurodegenerative diseases? / Sánchez de Groot, Natalia (Laboratory of Molecular Biology. Medical Research Council) ; Torrent Burgas, Marc (Laboratory of Molecular Biology. Medical Research Council) ; Universitat Autònoma de Barcelona. Departament de Bioquímica i Biologia Molecular
Systemic inflammation and infections are associated with neurodegenerative diseases. Unfortunately, the molecular bases of this link are still largely undiscovered. We, therefore, review how inflammatory processes can imbalance membrane homeostasis and theorize how this may have an effect on the aggregation behavior of the proteins implicated in such diseases. [...]

Una de les principals línies de recerca del grup és l'estudi del mal plegament i l'agregació de proteïnes relacionades amb la malaltia. Estudien aquest fenomen des d'un punt de vista biofísic, per conèixer les propietats de les proteïnes que estan involucrades en aquest esdeveniment, i també utilitzant models vius, per entendre la seva relació amb les malalties i les funcions cel·lulars.

Background: The amyloid-β peptide (Aβ42) is the main component of the inter-neuronal amyloid plaques characteristic of Alzheimer's disease (AD). The mechanism by which Aβ42 and other amyloid peptides assemble into insoluble neurotoxic deposits is still not completely understood and multiple factors have been reported to trigger their formation.

Background: The polypeptides involved in amyloidogenesis may be globular proteins with a defined 3D-structure or natively unfolded proteins. The first class includes polypeptides such as β2-microglobulin, lysozyme, transthyretin or the prion protein, whereas β-amyloid peptide, amylin or α-synuclein all belong to the second class. [...]
