Prolonged self-assembly of H. pylori ferritin globules at physiological conditions.

One of the promising drug delivery tools is ferritin, which features high stability at a wide range of conditions and protects cargo by its spherical protein shell. We studied the self-assembly into homoglobules of ferritin from H. pylori and a chimeric protein ferritin-SUMO.

Intraoral Ultrasonography for the Exploration of Periodontal Tissues: A Technological Leap for Oral Diagnosis.

Introduction: Periodontal disease is an infectious syndrome presenting inflammatory aspects. Radiographic evaluation is an essential complement to clinical assessment but has limitations such as the impossibility of assessing tissue inflammation. It seems essential to consider new exploration methods in clinical practice.

Ferritin-based fusion protein shows octameric deadlock state of self-assembly.

Ferritin is a universal protein complex responsible for iron perception in almost all living organisms and has applications from fundamental biophysics to drug delivery and structure-based immunogen design. Different platforms based on ferritin share similar technological challenges limiting their development - control of self-assembling processes of ferritin itself as well as ferritin-based chimeric recombinant protein complexes. In our research, we studied self-assembly processes of ferritin-based protein complexes under different expression conditions.

I-Shaped Dimers of a Plant Chloroplast FF-ATP Synthase in Response to Changes in Ionic Strength.

F-type ATP synthases play a key role in oxidative and photophosphorylation processes generating adenosine triphosphate (ATP) for most biochemical reactions in living organisms. In contrast to the mitochondrial FF-ATP synthases, those of chloroplasts are known to be mostly monomers with approx. 15% fraction of oligomers interacting presumably non-specifically in a thylakoid membrane.
