Innate defenses to virus infections are triggered by pattern recognition receptors (PRRs). The two cytoplasmic PRRs RIG-I and PKR bind to viral signature RNAs, change conformation, oligomerize, and activate antiviral signaling. Methods are described which allow to conveniently monitor the conformational switching and the oligomerization of these cytoplasmic PRRs.

This video describes the technique of aspirating bone marrow from iliac spine and smear preparation for biopsy. In the example, we perform bone marrow aspiration from an acute myeloid leukemia (AML) patient and examine the cells to check for measurable residual disease (MRD), an important prognostic biomarker.
FAQs
The hierarchy organizes bones into related levels so that movement at one joint can coordinate the position of connected skeletal elements. This structure reflects how anatomical parts work together during limb movement rather than treating each component as isolated. In a digital model, the hierarchy therefore helps represent linked motion clearly and supports interactive demonstrations of skeletal function.
Weight mapping assigns particular mesh regions to individual bones, determining which parts of the three-dimensional model respond when those bones move. This connects skeletal motion with visible changes in the surrounding model. In biology-focused visualizations, that relationship helps viewers examine how movement of the underlying skeletal structure affects the represented anatomy and improves interpretation of coordinated motion.
Joint rotations and translations provide the motion inputs that drive the rigged structure. Rotations can represent changes in angular position, while translations shift elements through space, allowing the model to display different anatomical poses. Using these controls makes it possible to visualize movement as an organized interaction among skeletal components and surrounding tissues instead of as a static structure.
A typical workflow begins by arranging the digital bones into a hierarchical skeletal system. The modeler then assigns mesh regions to the appropriate bones through weight mapping and tests joint rotations or translations to produce coordinated movement. The resulting rig can be adjusted for the intended anatomical representation, whether the goal is an educational animation, biomechanical model, or interactive dissection.
Bone rigging is useful when a project must communicate anatomy through motion rather than still images alone. Educational animations can demonstrate limb movement, while biomechanical modeling can represent relationships between skeletal structure and function. Virtual dissection and research communication also benefit because viewers can interact with anatomical representations and examine coordinated movement more directly.
A rigged model can clarify how skeletal structures guide limb movement and how they interact with surrounding tissues. By linking anatomical form to controlled motion, it helps users connect structure with function and observe coordinated changes in an interactive representation. This makes bone rigging relevant to teaching, visualization of anatomical motion, and communication of biological research findings.
