The recently described ESX-5 secretion system of Mycobacterium tuberculosis is one of the most important modulators of host-pathogen interactions due to its crucial impact on PPE protein secretion, cell wall stability and virulence. Although various components of the ESX-5 secretion machinery have been defined, other ESX-5 core components still remain to be(More)
We have previously demonstrated that a soluble form of the human NK cell natural cytotoxicity receptor NKp44, binds to the surface of Mycobacterium tuberculosis (MTB). Herein, we investigated the interaction of MTB cell wall components (CWC) with NKp44 or with Toll-like receptor 2 (TLR2) and the role of NKp44 and TLR2 in the direct activation of NK cells(More)
Mitochondria form a highly dynamic network driven by opposing scission and fusion events. DRP1 is an essential modulator of mitochondrial fission and dynamics within mammalian cells. Its fission activity is regulated by posttranslational modifications such as activating phosphorylation at serine 616. DRP1 activity has recently been implicated as being(More)
The use of recombinant antigens and chemically synthesized peptides are the new approaches for the construction of reliable and sensrtive diagnostic assays. Moreover, in the field of virology, the use of recombinant antigens eliminates the need to handle highly hazardous material in the preparation of the assays (1,2) and allows the assembly of multiepitope(More)
The use of recombinant antigens is essential for the construction of robust and sensitive diagnostic assays. A critical step in the preparation of recombinant antigens is protein purification. Purification problems may be very different for related structural proteins expressed in the same host or for the same protein expressed in different hosts, because(More)
Mycobacterium abscessus (MAB) is an emerging pathogen causing pulmonary infections in those with inflammatory lung disorders, such as Cystic Fibrosis (CF), and is associated with the highest fatality rate among rapidly growing mycobacteria (RGM). Phenotypically, MAB manifests as either a Smooth (MAB-S) or a Rough (MAB-R) morphotype, which differ in their(More)
