A facile, one-pot synthesis of N-succinimidyl-4-[18F]fluorobenzoate ([18F]SFB) was developed based on a non-aqueous, three-step radiochemical process. Using microwave heating, the entire procedure can be completed in less than 30 min, or 60 min with further purification by preparative HPLC. The decay-corrected radiochemical yields (RCYs) were 35-5% (n > 30).

Stable isotope labeling workflows employing 18O-enriched water (LeO-workflows) are versatile tools for quantitative and qualitative proteomics studies. In protease-assisted (PALeO) workflows, 18O-atoms are introduced by proteolytic cleavage and carboxyl oxygen exchange reactions mediated by proteases. In the acid-catalyzed (ALeO) workflow, 18O-atoms are introduced by carboxyl oxygen exchange at low pH.

FAQs
After IL-18 binds its receptor on a target immune cell, intracellular signaling pathways are activated and promote transcription of immune-response genes. This provides a molecular link between cytokine exposure and measurable cellular behavior. In experimental systems, examining downstream gene activity helps researchers connect receptor engagement with broader changes in immune activation during infection or inflammation.
IL-12 can cooperate with IL-18 to enhance interferon-gamma production by natural killer cells and T lymphocytes. This combined activity is important because it links cytokine signaling to a stronger response from both innate and adaptive immune cell populations. Comparing IL-18 with or without IL-12 can therefore clarify how these cytokines jointly regulate immune responses.
Natural killer cells and T lymphocytes are key populations because the IL-18 and IL-12 combination can enhance their interferon-gamma production. Studying these cells together provides insight into interactions between innate and adaptive immunity. Their responses can be evaluated through cytokine secretion and other indicators of activation, helping distinguish the contributions of different immune compartments.
An in vitro study exposes selected immune cells to IL-18, with IL-12 included when researchers want to examine cooperative cytokine effects. The resulting response is then assessed through cytokine secretion, immune-cell activation, or transcription of immune-response genes. This workflow allows investigators to connect a defined stimulation condition with measurable cellular and molecular outcomes.
Common experimental outcomes include cytokine secretion, immune-cell activation, and changes associated with transcription of immune-response genes. Interferon-gamma production is especially informative when natural killer cells or T lymphocytes receive IL-18 together with IL-12. These measurements show how target cells respond and help characterize the strength and nature of the induced immune activity.
Researchers can apply IL-18 stimulation to investigate host defense mechanisms during infection and to examine how innate and adaptive immunity interact. The same experimental strategy can support studies of inflammatory disorders and potential immunomodulatory therapies. By measuring cellular and cytokine responses under controlled conditions, investigators can explore how cytokine signaling shapes disease-relevant immune behavior.
