Porphyromonas gingivalis GroEL exacerbates orthotopic allograft transplantation vasculopathy via impairment of endothelial cell function

open access: yesMolecular Oral Microbiology, EarlyView.
Abstract Orthotopic allograft transplantation (OAT) is a significant approach to addressing organ failure. However, persistent immune responses to the allograft affect chronic rejection, which induces OAT vasculopathy (OATV) and organ failure. Porphyromonas gingivalis can infiltrate remote organs via the bloodstream, thereby intensifying the severity ...

Porphyromonas gingivalis GroEL accelerates abdominal aortic aneurysm formation by matrix metalloproteinase‐2 SUMOylation in vascular smooth muscle cells: A novel finding for the activation of MMP‐2

open access: yesMolecular Oral Microbiology, EarlyView.
Abstract Infection is a known cause of abdominal aortic aneurysm (AAA), and matrix metalloproteases‐2 (MMP‐2) secreted by vascular smooth muscle cells (SMCs) plays a key role in the structural disruption of the middle layer of the arteries during AAA progression.

In silico engineering of aggregation-prone recombinant proteins for substrate recognition by the chaperonin GroEL

open access: yesBMC Genomics, 2012
Background Molecular chaperones appear to have been evolved to facilitate protein folding in the cell through entrapment of folding intermediates on the interior of a large cavity formed between GroEL and its co-chaperonin GroES.

Protein evolution speed depends on its stability and abundance and on chaperone concentrations. [PDF]

open access: yes, 2018
Proteins evolve at different rates. What drives the speed of protein sequence changes? Two main factors are a protein's folding stability and aggregation propensity. By combining the hydrophobic-polar (HP) model with the Zwanzig-Szabo-Bagchi rate theory,

Rickettsiales in South America: A Systematic Review of Their Molecular Detection and Distribution in Arthropods and Vertebrates

open access: yesPublic Health Challenges, Volume 5, Issue 2, June 2026.
ABSTRACT Bacteria of the order Rickettsiales comprise a diverse group of obligate intracellular microorganisms that are globally distributed and highly prevalent in tropical and subtropical regions. In South America, these bacteria have been associated with arthropod vectors, such as ticks, fleas, mites, lice, and certain dipterans, as well as with a ...

Latent Neoehrlichia mikurensis Infections May Be Reactivated in Patients With B‐Cell Lymphomas Treated With Rituximab

open access: yesImmunology, Volume 178, Issue 2, Page 307-317, June 2026.
Eight percent of this cohort of patients had a latent Neoehrlichia mikurensis infection. It was only the latently infected patients who had N. mikurensis‐specific T cells, not the matched B‐cell lymphoma patients without the infection. The T‐cell responses of latently infected patients included perforin‐expressing Th1 and CD8+ T cells that upregulated ...
