Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Dendritic cells exhibit low migration ability to lymph nodes, limiting their effectiveness in activating T cells and treating immune-related diseases.

Innovation Solution

Contact immature dendritic cells with autotaxin to induce maturation and enhance migration ability, using a method that includes culturing imDCs with autotaxin in an RPMI medium, optionally with LPS and KLH, for 1-48 hours, to produce mature dendritic cells (mDCs) with increased migration capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dendritic cells are used for immune therapy, then immune response induction is improved, but migration ability to lymph nodes is insufficient

Engineering Contradiction:

Improveimmune response inductionVSAvoidmigration ability

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

The patent changes the biochemical parameters of dendritic cells by treating them with autotaxin and LPS, which modifies their surface markers (increasing CCR7 expression) and functional properties. This parameter change enables the cells to overcome their natural low migration tendency while maintaining their immune activation capability, thus resolving the contradiction between reliable immune response induction and sufficient migration speed to lymph nodes

Inventive Principle:

2Productivity

If immature dendritic cells are used, then cell collection function is maintained, but T cell activation ability is insufficient

Engineering Contradiction:

Improveantigen collectionVSAvoidT cell activation

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by treating dendritic cells with autotaxin and LPS before their therapeutic application. This pre-treatment induces maturation changes that enable T cell activation while the cells still retain their antigen collection capability. The preliminary biochemical modification resolves the contradiction between maintaining antigen collection function and acquiring T cell activation ability

AI summary

A method for increasing dendritic cell migration ability, and a use thereof are disclosed. A method according to one aspect can increase the migration ability of mature dendritic cells and increase the induction, by dendritic cells, of inflammatory cytokine production, T lymphocyte proliferation and T lymphocyte polarization, and thus can be used for the prevention or treatment of immune-related diseases.
