Due to anatomical and biological similarities with humans, pigs are increasingly used for inflammation- and immune-related studies in biomedical research, including the field of osteonecrosis and osteoimmunology. Here, we present a protocol for rib extraction, isolation of the bone marrow by centrifugation, and processing to obtain bone-marrow-derived macrophages (BMDMs). Then, we describe the procedures of in vitro experiments to evaluate the cell phenotype. For complete details on the use and execution of this protocol, please refer to Andre et al..

Macrophage-based cell therapies represent a cutting-edge frontier in immunotherapy, offering distinct advantages over conventional approaches like CAR-T. This review explores the potential of macrophages to orchestrate both innate and adaptive immune responses, enhancing the body's ability to combat diseases locally and systemically. Dubbed a "Smart Cell Therapy," macrophages can initiate and coordinate complex immunological cascades, leveraging multiple immune system components while also performing effector functions.

African swine fever (ASF) is a lethal disease of domestic pigs that is currently challenging swine production in large areas of Eurasia. The causative agent, ASF virus (ASFV), is a large, double-stranded and structurally complex virus. The ASFV genome encodes for more than 160 proteins; however, the functions of most of these proteins are still in the process of being characterized.

Mandarin fish ranavirus (MRV) is a distinctive member among the genus of the family . The persistently covert infection of MRV was previously observed in a natural outbreak of MRV, but the underlying mechanism remains unclear. Here, we show that mandarin fish peripheral B lymphocytes are implemented as viral reservoirs to maintain the persistent infection.

HIV-1 subtype C viruses are responsible for 50% of global HIV burden. However, nearly all currently available reporter viruses widely used in HIV research are based on subtype B. We constructed and characterized a replication-competent HIV-1 subtype C reporter virus expressing mGreenLantern.

The mechanisms of the innate immunity control of equine infectious anemia virus in horses are not yet widely described. Equine monocytes isolated from the peripheral blood of three Equine infectious anemia (EIA) seronegative horses were differentiated in vitro into macrophages that gave rise to mixed cell populations morphologically referable to M1 and M2 phenotypes. The addition of two equine recombinant cytokines and two EIA virus reference strains, Miami and Wyoming, induced a more specific cell differentiation, and as for other species, IFNγ and IL4 stimulation polarized horse macrophages respectively towards the M1 and the M2 phenotypes.
