Detection of live African swine fever virus (ASFV) has historically relied on the use of primary swine macrophages (PSM). PSM do not replicate and have to be isolated fresh from donor swine. We previously identified that a MA-104 cells (ATCC #CRL-2378.1), a commercially available cell line isolated from African green monkey (Cercopithecus aethiops) kidney epithelial cells, supports the detection of ASFV from field samples with a sensitivity comparable to that of primary swine macrophages. Collection of swine blood or lungs is time costing, which is often not readily available in most veterinary diagnostic laboratories. MA-104 cells could thus be used as substitute for primary swine macrophages to save significant lead time by avoiding the production of primary swine macrophages.

Human induced pluripotent stem cells (iPSCs) and their progeny displaying tissue-specific characteristics have paved the way for regenerative medicine and research in various fields such as the elucidation of the pathological mechanism of diseases and the discovery of drug candidates. iPSC-derived neurons are particularly valuable as it is difficult to analyze neural cells obtained from the central nervous system in humans. For neuronal induction with iPSCs, one of the commonly used approaches is the isolation and expansion of neural rosettes, following the formation of embryonic bodies (EBs). However, this process is laborious, inefficient, and requires further purification of the cells. To overcome these limitations, we have developed an efficient neural induction method that allows for

Immune tolerance and response are both largely driven by the interactions between the major histocompatibility complex (MHC) expressed by antigen presenting cells (APCs), T-cell receptors (TCRs) on T-cells, and their cognate antigens. Disordered interactions cause the pathogenesis of autoimmune diseases such as type 1 diabetes. Therefore, the identification of antigenic epitopes of autoreactive T-cells leads to important advances in therapeutics and biomarkers. Next-generation sequencing methods allow for the rapid identification of thousands of TCR clonotypes from single T-cells, and thus there is a need to determine cognate antigens for identified TCRs. This protocol describes a reporter system of T-cell activation where the fluorescent reporter protein ZsGreen-1 is driven by nuclear
