Two-hybrid screening is a standard methodology to identify and characterize protein-protein interactions that has become an integral component of many proteomic investigations. The twohybrid system was initially developed using yeast as a host organism. However, bacterial two-hybrid systems have also become common laboratory tools and are preferred in some circumstances, although yeast and bact...

Background: Toll like receptors (TLRs) are a major family of innate immune systems which recognize specific pathogen associated molecular patterns (PAMPS)in bacterial, fungi, virus and parasites. Human TLRs comprise a large family of 10 different type proteins that are expressed on various immune cells. Among these receptors, TLR1, 2, 4, 5, 6 and 10 were expressed on the cell surface. TLR2 form...

Background: Uncontrolled cell proliferation and resistance to apoptosis are the main characteristics of cancer cells. Therefore, a substance with the capability to induce apoptosis in cancer cells could be known as an anti-cancer material. Probiotics are useful microorganisms that are crucial for the host’s health.Materials and Methods: In the present stu...

Abstract With the advancement of genetic engineering, monoclonal antibodies (mAbs) have made far-reaching progress in treatment various human diseases. However, due to high cost production, increasing demands for antibody-based therapies not been fully met. Currently, mAb-derived alternatives, such as antigen-binding fragments (Fab), single-chain variable fragments, bispecifics, nanobodies, and...

Bacterial transcriptomics is widely used to investigate gene regulation, bacterial susceptibility to antibiotics, host-pathogen interactions, and pathogenesis. Transcriptomics is crucially dependent on suitable methods to isolate and detect bacterial RNA. Microfluidics offer ways of creating integrated point-of-care systems, analysing a sample from preparation, and RNA isolation to detection. A...

Bacterial cells sense their population density and respond accordingly by producing various signal molecules to the surrounding environments thereby trigger a plethora of gene expression. This regulatory pathway is termed quorum sensing (QS). Plenty of bacterial virulence factors are controlled by QS or QS-mediated regulatory systems and QS signal molecules (QSSMs) play crucial roles in bacteri...

Bacterial-based systems as live vectors for the delivery of heterologous antigens offer a number of advantages as vaccination strategies. Developments in genetic engineering have given Gram-positive lacticacid bacteria (LAB) the advantage of being used as a host expression system for antigen delivery to inducethe immune response. A fragment containing the full length of the “eprA1” ...
