The basis of MreB research is the study of the MreB protein from the species, since it was the first one whose crystal structure was described. Since MreB proteins from different bacterial species show different polymerisation properties in terms of nucleotide and salt dependence, we conducted our research in this direction. For this, we performed measurements based on tryptophan emission, which were supplemented with temperature-dependent and chemical denaturation experiments. The role of nucleotide binding was studied through the fluorescent analogue TNP-ATP. These experiments show that MreB is stabilised in the presence of low salt buffer and ATP. In the course of our work, we developed a new expression and purification procedure that allows us to obtain a large amount of pure, functional protein.

The relation in MreB and intrabacterial nanotransportation system for VacA in Helicobacter pylori.

Med Mol Morphol

December 2024

Project Team for Study of Nanotransportation System, Center for Medical Research and Development, Osaka Medical and Pharmaceutical University, 2-7 Daigaku-Machi, Takatsuki, Osaka, 569-8686, Japan.

Helicobacter pylori possesses an intrabacterial nanotransportation system (ibNoTS) for transporting VacA, CagA, and urease within the bacterial cytoplasm. This system is controlled by the extrabacterial environment. The transport routes of the system for VacA have not yet been studied in detail.

Unlabelled: Understanding the mechanisms that dictate the localization of cytoskeletal filaments is crucial for elucidating cell shape regulation in prokaryotes. The actin homolog MreB plays a pivotal role in maintaining the shape of many rod-shaped bacteria such as by directing cell-wall synthesis according to local curvature cues. However, the basis of MreB's curvature-dependent localization has remained elusive.

Harnessing Bacterial Agents to Modulate the Tumor Microenvironment and Enhance Cancer Immunotherapy.

Cancers (Basel)

November 2024

Department of Microbial Pathogenesis and Immunology, Texas A&M University Health Science Center, MREB II, Room 3344, 8447 John Sharp Parkway, Bryan, TX 77807, USA.

Cancer immunotherapy has revolutionized cancer treatment by leveraging the immune system to attack tumors. However, its effectiveness is often hindered by the immunosuppressive tumor microenvironment (TME), where a complex interplay of tumor, stromal, and immune cells undermines antitumor responses and allows tumors to evade immune detection. This review explores innovative strategies to modify the TME and enhance immunotherapy outcomes, focusing on the therapeutic potential of engineered bacteria.

Article Synopsis
  • - MreB is an important protein in bacteria that helps maintain cell shape, and understanding its dynamics and interactions with membranes is crucial for studying bacterial biology.
  • - Research has been limited due to challenges in purifying MreB, but scientists successfully extracted it from a bacteria called ScMreB5 using E. coli, achieving high concentrations of the stable protein for further study.
  • - The developed purification protocol not only enhances protein yield and stability through optimized buffer conditions but also provides insights into how ions affect protein stability, which can be applied to other similar proteins.

Article Synopsis
  • Serovar L2 (Ct) divides through a unique polarized budding process instead of traditional binary fission, due to its lack of FtsZ, a protein common in other bacteria.
  • The assembly of the divisome, essential for cell division, is initiated by FtsK, which forms specific focal points at the site where new daughter cells will emerge, signifying its role in the division process.
  • Research indicates that FtsK is crucial for recruiting other proteins to the divisome, while MreB, though necessary for forming peptidoglycan rings, does not serve as the primary scaffold for divisome assembly.
