Host-and virus-derived factors are key drivers of the COVID-19 pandemic(Gortázar et al.).1 The interaction between the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)spike glycoprotein(S)and host cell membrane angiotensin I converting enzyme 2(ACE2)receptor is highly dynamic,mediates virus infection,and is the main target for protective antibody response2.

Background Artificial insemination(AI)is a routine breeding technology in animal reproduction.nevertheless,the temperature-sensitive nature and short fertile lifespan of ram sperm samples hamper its use in AI.In this sense,nanotechnology is an interesting tool to improve sperm protection due to the development of nanomaterials for AI,which could be used as delivery vehicles.In this work,we explored the feasibility of vitamin E nanoemulsion(nE)for improving sperm quality during transport.Results With the aim of evaluating this proposal,ejaculates of 7 mature rams of Manchega breed were collected by artificial vagina and extended to 60×10^(6)spz/mL in AndromedR.Samples containing control and nE(12 mmol/L)with and without exogenous oxidative stress(100μmol/L Fe2+/ascorbate)were stored at 22 and 15℃and motility(CASA),viability(yO-PRO/PI),acrosomal integrity(PnA-FITC/PI),mitochondrial membrane potential(Mitotracker deep Red 633),lipoperoxidation(C11 BODIPy 581/591),intracellular reactive oxygen species(ROS)production and DnA status(SCSAR)monitored during 96 h.Our results show that nE could be used to maintain ram spermatozoa during transport at 15 and 22℃for up to 96 h,with no appreciable loss of kinematic and physiological characteristics of freshly collected samples.Conclusions The storage of ram spermatozoa in liquid form for 2-5 d with vitamin E nanoemulsions may lead more flexibility to breeders in AI programs.In view of the potential and high versatility of these nanodevices,further studies are being carried out to assess the proposed sperm preservation medium on fertility after artificial insemination.

Gene expression changes in spleens of the wildlife reservoir species,Eurasian wild boar(Sus scrofa),naturally infected with Brucella suis biovar 2

Brucella suis is responsible for swine brucellosis worldwide. Of the five different B. suis biovars （by.）, bv. 2 appears restricted to Europe where it is frequently isolated from wild boar and hares, can infect pigs and can cause human brucellosis. In this study, the differ- ential gene expression profile was characterized in spleens of Eurasian wild boar naturally infected with B. suis bv. 2. Of the 20,201 genes analyzed in the microarray, 633 and 1,373 were significantly （fold change 〉 1.8; P 〈 0.01） upregulated and downregulated, respectively, in infected wild boar. The analysis was focused on genes that were over represented after conditional test for biological process gene ontology. Upregulated genes suggested that B. suis bv. 2 infection induced cell maturation, migration and/or proliferation in infected animals. The genes downregulated in infected wild boar impaired the activity of several important cellular metabolic pathways such as metabolism, cytoskeleton organization and biogenesis, immune response and lysosomal function and vesicle-mediated transport. In addition, the response to stress, sperm fertility, muscle development and apoptosis seemed to be also impaired in infected animals. These results suggested that B. suis bv. 2 may use strategies similar to other smooth brucellae to facilitate intracellular multiplication and the development of chronic infections. To our knowledge, this is the first report of the analysis of gene expression profile in hosts infected with B. suis bv. 2, which is important to understand the molecular mechanisms at the host-pathogen interface in the main reservoir species with possible implications in the zoonotic cycle of the pathogen.
