Article Abstract
In this report, we describe the recombinant SLO expression as a fusion protein with a C-terminal hexahistidine tag and its purification using immobilized metal affinity expanded bed adsorption (STREAMLINE(trade mark) Chelating). In order to facilitate downstream processing of the purification, an efficient fermentation process was developed focusing on the achievement of high yields of soluble protein. The purification strategy resulted in a 40% recovery of active recombinant SLO and the protein was purified eight-fold. SDS-PAGE and Western-blot analysis of the purified protein revealed the presence of a 75 Mr form, which was the estimated relative Mass of the recombinant SLO.

Diet gel-based oral drug delivery system for controlled dosing of small molecules for microglia depletion and inducible Cre recombination in mice.

Small molecules like PLX5622 for microglia depletion and Tamoxifen for inducible Cre recombination are commonly used in mouse research. Traditional application methods, such as chow or oral gavage and injections, have limitations, including uncontrolled dosage and risk of injury. To address this issue, we have developed an alternative oral drug delivery system using a gel-based rodent maintenance diet that allows for controlled consumption and adjustment of dosage and is suitable for water-insoluble small molecules.

Unlabelled: The World Health Organization's goal to combat tuberculosis (TB) is hindered by the emergence of anti-microbial resistance, therefore necessitating the exploration of new drug targets. Multidrug regimens are indispensable in TB therapy as they provide synergetic bactericidal effects, shorten treatment duration, and reduce the risk of resistance development. The research within our European RespiriTB consortium explores energy metabolism to identify new drug candidates that synergize with bedaquiline, with the aim of discovering more efficient combination drug regimens.

Background: Monkeypox Virus (MPV) is the cause of zoonotic disease characterized by skin-eruption with pus cell formation and lymphadenopathy. This virus belongs to the Orthopoxvirus genus with DNA as its genetic material. Previously, this infection was reported from Africa and occasionally from USA and UK.

Article Synopsis
- Planarians are being studied for their ability to regenerate, with new tools for expressing non-native proteins proving to be valuable for research.
- The study utilizes a luminescent reporter to avoid the strong autofluorescence in planarian tissues, facilitating the introduction and measurement of mRNA in living planarians.
- By modifying untranslated regions (UTRs) and investigating protein expression, this research lays the groundwork for understanding gene regulation and enhances methods for using planarians in genetic studies.

Under the need for new functional and biocompatible materials for biomedical applications, protein engineering allows the design of assemblable polypeptides, which, as convenient building blocks of supramolecular complexes, can be produced in recombinant cells by simple and scalable methodologies. However, the stability of such materials is often overlooked or disregarded, becoming a potential bottleneck in the development and viability of novel products. In this context, we propose a design strategy based on in silico tools to detect instability areas in protein materials and to facilitate the decision making in the rational mutagenesis aimed to increase their stability and solubility.
