Described here is a method for producing exogenous cytokine in patient-derived xenograft (PDX) mice via weekly intraperitoneal injection of a cytokine-transduced stromal cell line. This method broadens the utility of PDX and provides the option for transient or sustained exogenous cytokine delivery in a multitude of PDX models.

We describe a protocol to measure the antiviral cytokine production in mice infected with a model herpesvirus, murine gamma herpesvirus 68 (γHV68) that is closely-related to human Kaposi’s sarcoma-associated herpesvirus (KSHV) and Epstein-Barr virus (EBV). Utilizing genetically modified mouse strains and mouse embryonic fibroblasts (MEFs), we assessed the antiviral cytokine production both in vivo and ex vivo. “Reconstituting” the expression of innate immune components in knockout embryonic...

We illustrate the application of 1H(15N,αγ)12C resonant nuclear reaction analysis (NRA) to quantitatively evaluate the density of hydrogen atoms on the surface, in the volume, and at an interfacial layer of solid materials. The near-surface hydrogen depth profiling of a Pd(110) single crystal and of SiO2/Si(100) stacks is described.
FAQs
A capture antibody first binds the target cytokine, while a detection antibody binds the captured material and produces a measurable signal. The signal intensity is compared with results from known cytokine standards, allowing researchers to estimate the amount present in an unknown sample. This antibody-pair arrangement links molecular recognition to quantitative analysis.
A calibrated standard curve provides the reference needed to convert an assay signal into an estimated cytokine concentration. Unknown serum, plasma, culture, or tissue samples are interpreted by comparing their signals with standards measured in the same assay. Without this calibration step, signal intensity would not provide a meaningful quantitative result.
ELISA and multiplex bead-based platforms both use capture and detection antibodies, but they support different measurement strategies. An ELISA generally focuses on a target cytokine, whereas multiplex platforms can assess patterns across multiple cytokines in a sample. That broader profile can help characterize coordinated immune activation or dysregulation rather than a single analyte alone.
Measured levels can vary with sample type, collection timing, processing, and biological context. Serum, plasma, cell-culture supernatants, and tissue samples may represent different aspects of an immune response, while infection or treatment status can alter cytokine patterns. Interpreting a concentration therefore requires attention to how and when the sample was obtained.
A typical workflow begins by selecting an appropriate serum, plasma, culture-supernatant, or tissue sample and an antibody-based assay suited to the target or targets of interest. The sample is analyzed alongside calibrated standards and assay controls, then its signal is compared with the standard curve. Results can subsequently be compared across disease, treatment, or experimental groups.
The measurements help researchers characterize host responses during infection, compare disease states, evaluate treatment effects, and identify patterns of immune dysregulation. In cell-culture experiments, supernatant measurements can indicate signaling released by stimulated cells, while clinical or tissue samples provide context for responses in affected organisms. Interpretation is strongest when concentration patterns are considered with biological timing and sample context.
