CFSE covalently labels long-lived intracellular molecules with the fluorescent dye, carboxyfluorescein. As such, when a CFSE-labeled cell divides, its progeny have half the amount of fluorescence, which can thereby be used to assess cell division. This article describes the procedures typically used for labeling mouse lymphocytes with CFSE.

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

In this protocol a method to measure intracellular protein refolding after heat shock is described. This method can be used to study foldases like molecular chaperones and their co-factors or compounds able to influence their activity. Firefly luciferase activity is used as reporter to measure chaperone refolding activity.

This video demonstrates a monocyte-derived dendritic cell, MoDC-based assay to measure the immunogenicity of commercially available vaccines. MoDC assays investigate dendritic cell responses to antigens, pathogens, or treatments and can provide insights into immune responses, vaccine development, and immunotherapy research.
FAQs
The cellular compartment strongly shapes pathogen survival and growth. A microorganism may replicate in the cytosol or within a membrane-bound vacuole, and each location presents different conditions and defensive barriers. Occupying a compartment that avoids lysosomal destruction can support persistence, allowing intracellular proliferation to continue despite cellular mechanisms that would otherwise degrade invading microbes.
Avoiding lysosomal destruction preserves the pathogen’s ability to remain viable inside the host cell. Lysosomes provide a destructive pathway that can eliminate invading microorganisms, so bypassing or avoiding this pathway gives the pathogen time to multiply. This mechanism is important because it links intracellular survival with prolonged infection and helps explain how pathogens evade an early cellular defense.
Intracellular pathogens can redirect host nutrients and cellular machinery toward their own replication. This dependence on host resources makes the infected cell both a protective environment and a source of materials needed for multiplication. It also creates potential cellular targets for limiting infection, because disrupting the pathogen’s access to host support may reduce proliferation or persistence.
Researchers measure intracellular growth to determine whether microorganisms survive and multiply within host cells. These measurements can clarify pathogen survival strategies and reveal how effectively host cells restrict infection. Comparing intracellular growth under different experimental conditions also helps investigators examine immune effects, assess antimicrobial treatments, and identify changes associated with pathogen persistence.
Intracellular growth studies provide an outcome for evaluating whether antimicrobial treatments restrict microorganisms after they enter host cells. They can also help assess vaccines by revealing whether immune protection limits pathogen persistence or multiplication. Because the measurements connect treatment or vaccination with cellular infection outcomes, they support comparisons of strategies designed to control infection and prevent its spread.
Changes in intracellular proliferation can show how innate and adaptive immunity influence infection after microorganisms enter host cells. These studies help distinguish pathogen survival strategies from host-cell responses and can identify cellular targets involved in restricting growth. In immunology and infection research, that information connects microbial persistence with the broader mechanisms that control infection and its spread.
