Abstract
Serpins represent one of the most diverse families of serine protease inhibitors. Despite their complexity, they are virtually found in all organisms and play an important role in homeostasis processes such as blood coagulation, inflammation, fibrinolysis, immune responses, chromatin condensation, tumor suppression, and apoptosis. There has recently been particular interest in studying serpin functions in infection and inflammation, especially since more serpins from parasites have been identified and characterized. Among helminths, Trichinella spiralis is one of the few parasites with an extremely strong ability to induce host immune suppression. Previous studies show that serpins are present in Trichinella and are expressed differentially at different parasite stages. More interesting, there is evidence of a recombinant serpin from Trichinella pseudospiralis that alters macrophage polarization in vitro. This finding could be relevant to comprehend the modulation process of the immune response. We expressed Tsp_01570, a putative serpin gene from Trichinella spiralis, in the eukaryotic system Pichia pastoris SMD1168H and evaluated its presence at different parasite stages, finding the serine protease inhibitor in the crude extract of adult worms. The effect of recombinant serpin on THP-1 cells was tested by quantification of IL-12p40, TNF-α, IL-4, and IL-10 cytokines released by ELISA. We also evaluated the expression of the M1 markers, CCR7 and CD86, and the M2 markers, CD163 and CD206, by immunofluorescence staining. This study represents the first insight in elucidating the importance of serpin Tsp_01570 as a potential molecular modulator.

Expression of recombinant protease MarP from Mycobacterium tuberculosis in Pichia pastoris and its effect on human monocytes. Biotechnol Lett 2021; 43:1787-1798.

Abstract
OBJECTIVE Mycobacterial acid-resistant protease (MarP) is a membrane-associated serine protease involved in the survival of Mycobacterium tuberculosis in macrophages; here we produced MarP in the yeast Pichia pastoris and study its involvement in macrophage immune modulation. RESULTS Pichia pastoris vectors, harboring a full-length or a partial sequence of MarP, were constructed. GS115 clones were selected, and homologous recombination at the AOX1 locus was assessed by PCR. Protein was purified by nickel affinity chromatography, and its effect on the cytokine profile was tested in human monocytes. Only the partial MarP protein (121-397 a.a.) lacking the transmembrane domain was successfully expressed as an N-glycosylated proteolytically active protease. In vitro stimulation of THP-1 cells with MarP promoted the release of TNF-α and IL-10. CONCLUSION Mycobacterial MarP was successfully expressed in P. pastoris, and it is capable of cytokine release in vitro.
