Generation and functional characterization of bovine bone marrow-derived macrophages

Abstract

A culture system for bovine bone marrow derived macrophages (BBMM) was devised, starting with bone marrow cells from tibiae of calf fetuses of over 6 months gestation. Tibiae removed aseptically were sawed open, and the bone marrow was collected, washed and placed in hydrophobic (teflon) containers, thereby allowing the propagation and differentiation of macrophage lineage cells. All other cell types were negatively selected for. This results in enriched macrophage populations between 12 and 18 days of culture which were suitable for use in functional studies. The culture system was strictly serum-dependent but independent of the addition of conditioned medium containing macrophage colony-stimulating factor. The cells were mature macrophages by morphological and histochemical criteria. They expressed CD14 and CD11b, two typical macrophage markers. They were positive for CD18 and CD36 and bound monomeric murine IgG2a, indicating that a high-affinity Fc receptor for this isotype is expressed by bovine macrophages. The cells ingested erythrocytes opsonized by rabbit IgG, human IgG, bovine IgG1 and IgG2. Upon triggering with opsonized zymosan or phorbol 12-myristate 13-acetate, reactive oxygen species were generated. Upon triggerin...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Hereditary Sensory Autonomic Neuropathy

Hereditary Sensory Autonomic Neuropathies are a group of inherited neurodegenerative disorders characterized clinically by loss of sensation and autonomic dysfunction. Here is the latest research on these neuropathies.

Spatio-Temporal Regulation of DNA Repair

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.

Glut1 Deficiency

Glut1 deficiency, an autosomal dominant, genetic metabolic disorder associated with a deficiency of GLUT1, the protein that transports glucose across the blood brain barrier, is characterized by mental and motor developmental delays and infantile seizures. Follow the latest research on Glut1 deficiency with this feed.

Separation Anxiety

Separation anxiety is a type of anxiety disorder that involves excessive distress and anxiety with separation. This may include separation from places or people to which they have a strong emotional connection with. It often affects children more than adults. Here is the latest research on separation anxiety.

KIF1A Associated Neurological Disorder

KIF1A associated neurological disorder (KAND) is a rare neurodegenerative condition caused by mutations in the KIF1A gene. KAND may present with a wide range and severity of symptoms including stiff or weak leg muscles, low muscle tone, a lack of muscle coordination and balance, and intellectual disability. Find the latest research on KAND here.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.
