2019
Overview Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors. Genetic Information Flows from DNA to RNA to Protein A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

Microarrays are important tools for profiling gene expression, and are based on complementary binding between probes that are attached to glass chips and nucleic acids derived from samples. Using these arrays, scientists can simultaneously evaluate the expression of thousands of genes. In addition, the expression profiles of different cells or tissue types can be compared, allowing researchers to deduce how the expression of different genes change during biological processes, and thus gain...

2023
Gene expression is the complex process where a cell uses its genetic information to make functional products. This process is regulated at multiple stages, and any misregulation could lead to diseases such as cancer. This video highlights important historical discoveries relating to gene expression, including the understanding of how distinct combinations of DNA bases encode the amino acids that make up proteins. Key questions in the field of gene expression research are explored, followed by a...

The segmentation clock drives oscillatory gene expression across the pre-somitic mesoderm (PSM). Dynamic Notch activity is key to this process. We use imaging and computational analyses to extract temporal dynamics from spatial expression data to demonstrate that Delta ligand and Notch receptor expression oscillate in the vertebrate PSM.
FAQs
CD86 can support different outcomes because it interacts with CD28 and CTLA-4, which have opposing effects on T-cell responses. CD28 binding supports T-cell activation, whereas CTLA-4 binding helps limit or modulate that response. Consequently, increased CD86 expression signals greater potential for co-stimulatory communication, but its biological effect depends on which receptor interaction predominates.
Activated dendritic cells, macrophages, and B cells typically increase CD86 expression, linking this measurement with changes in antigen-presenting capacity. The marker therefore helps researchers compare immune-cell states and assess whether cells have become more activated. In this context, CD86 provides information about immune regulation rather than serving as an isolated measure of every cellular function.
CD86 expression reflects a regulatory interface between antigen-presenting cells and T cells. Through CD28, it can contribute to T-cell activation, while interaction with CTLA-4 can limit or modulate that response. Measuring the protein therefore helps place T-cell behavior within a broader immune-cell interaction, rather than treating activation as an independent event.
Flow cytometry, immunostaining, and molecular assays are established approaches for measuring CD86 expression. These methods allow investigators to examine CD86 production or display in biological samples and relate the result to immune-cell activation or antigen-presenting capacity. Selecting among them enables studies to characterize the marker across different experimental designs and sample types.
Researchers can use CD86 measurements to characterize activation-associated changes in dendritic cells, macrophages, or B cells. Comparing expression across experimental conditions can indicate differences in antigen-presenting capacity and immune regulation. The resulting data are especially useful when investigators need a marker-based assessment of how cells respond during studies of infection, vaccination, autoimmunity, or cancer.
CD86 expression provides a way to examine how immunomodulatory therapies affect communication between antigen-presenting cells and T cells. Because CD86 can support activation through CD28 or modulate responses through CTLA-4, changes in its measured level may help characterize treatment-associated effects on immune regulation. This makes it relevant to biomedical studies of therapies that alter immune responses.
