Abstract
In recent years, multiple coronaviruses have emerged, with the latest one, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing a global pandemic. Besides respiratory symptoms, some patients experienced extrapulmonary effects, such as cardiac damage or renal injury, indicating the broad tropism of SARS-CoV-2. The ability of the virus to effectively invade the renal cellular environment can eventually cause tissue-specific damage and disease. Indeed, patients with severe coronavirus disease 2019 exhibited a variety of symptoms such as acute proximal tubular injury, ischemic collapse, and severe acute tubular necrosis resulting in irreversible kidney failure. This review summarizes the current knowledge on how it is believed that SARS-CoV-2 influences the renal environment and induces kidney disease, as well as current therapy approaches.

Abstract
Differences in immune response between men and women may influence the outcome of infectious diseases. Intestinal infection with Entamoeba histolytica leads to hepatic amebiasis, which is more common in males. Previously, we reported that innate immune cells contribute to liver damage in males in the murine model for hepatic amebiasis. Here, we focused on the influences of sex and androgens on neutrophils in particular. Infection associated with neutrophil accumulation in the liver was higher in male than in female mice and further increased after testosterone treatment in both sexes. Compared with female neutrophils, male neutrophils exhibit a more immature and less activated status, as evidenced by a lower proinflammatory N1-like phenotype and deconvolution, decreased gene expression of type I and type II interferon stimulated genes (ISGs) as well as downregulation of signaling pathways related to neutrophil activation. Neutrophils from females showed higher protein expression of the type I ISG viperin/RSAD2 during infection, which decreased by testosterone substitution. Moreover, ex vivo stimulation of human neutrophils revealed lower production of RSAD2 in neutrophils from men compared with women. These findings indicate that sex-specific effects on neutrophil physiology associated with maturation and type I IFN responsiveness might be important in the outcome of hepatic amebiasis.

Abstract
Different protein purification methods exist. Yet, they need to be adapted for specific downstream applications to maintain functional integrity of the recombinant proteins. This study established a purification protocol for lentiviral Vpx (viral protein X) and test its ability to degrade sterile alpha motif and histidine-aspartate domain-containing protein 1 (SAMHD1) ex vivo in resting CD4+ T cells. For this purpose, we cloned a novel eukaryotic expression plasmid for Vpx including C-terminal 10x His- and HA-tags and confirmed that those tags did not alter the ability to degrade SAMHD1. We optimized purification conditions for Vpx produced in HEK293T cells with CHAPS as detergent and Co-NTA resins yielding the highest solubility and protein amounts. Size exclusion chromatography (SEC) further enhanced the purity of recombinant Vpx proteins. Importantly, nucleofection of resting CD4+ T cells demonstrated that purified recombinant Vpx protein efficiently degraded SAMHD1 in a proteasome-dependent manner. In conclusion, this protocol is suitable for functional downstream applications of recombinant Vpx and might be transferrable to other recombinant proteins with similar functions/properties as lentiviral Vpx.
