This method for isolating functional immune cells from the heart provides an alternative to the conventional methods of collagenase digestion, which causes unwanted immune cell activation, resulting in a decreased responsiveness of these cells. Our method of isolation yields functional cardiac immune cells by avoiding problems associated with enzymatic digestion.

Herein we describe two approaches to characterize cell polarization events in B lymphocytes during the formation of an IS. The first, involves quantification of organelle recruitment and cytoskeleton rearrangements at the synaptic membrane. The second is a biochemical approach, to characterize changes in composition of the centrosome, which undergoes polarization to the immune synapse.

Microglia are resident macrophages that provide the first line of defense and immune surveillance of the central nervous system. MicroRNAs are regulatory molecules that play an important role in many physiological processes including activation and differentiation of macrophages. In this article, we describe the method for measurement of microRNAs in microglia.
FAQs
Microglia continuously survey neural tissue and can respond when they detect pathogens or injury. Activation brings several coordinated functions into play, including phagocytosis, cytokine signaling, and antigen presentation. Together, these activities allow microglia to participate in local defense and communicate changes within the central nervous system rather than acting only as passive resident cells.
Infection or disruption of the blood-brain barrier can permit circulating leukocytes to cross into the brain or spinal cord. Once recruited, these cells join the response already coordinated by resident microglia. This distinction helps explain how local surveillance and newly arrived immune activity become integrated during conditions that challenge central nervous system tissue.
Inflammation protects neural tissue by coordinating responses to pathogens and injury, but it can also damage the tissue it is meant to defend. The same immune signaling and cellular activities that support protection may therefore become harmful when inflammation is not appropriately regulated. This balance is central to understanding infection and inflammatory disease in the nervous system.
Resident microglia are positioned within neural tissue and continuously survey their surroundings before a challenge occurs. Recruited leukocytes originate in the circulation and can enter when infection or blood-brain barrier disruption allows access. Comparing these populations clarifies how an established local response differs from the additional immune activity brought into the central nervous system.
A useful investigation can follow whether microglia recognize a pathogen or injury, activate phagocytosis, release cytokine signals, and present antigens. It can also assess whether circulating leukocytes cross the blood-brain barrier and join the response. Examining these linked events shows how immunity is coordinated within neural tissue and how inflammation develops.
These cells provide a framework for investigating neuroinfections, autoimmune disorders, neurodegeneration, and targeted therapy development. Their study can reveal how protective immune functions are organized in the brain and spinal cord, how inflammation may contribute to disease, and which cellular responses could be relevant when designing more focused therapeutic strategies.
