In 2011, Ralph Steinman received Novel prize for his discovery of dendritic cells and its role in adaptive immunity which can be used for the cancer immunotherapy. <br> <br> <font size="14pt"> What is cancer immunotherapy?</font> <br> Cancer immunotherapy induces the immune system to reject and destroy tumors. <br>表:Merits Problems <br>(Merits) <br>(Problems)Induced immune cells that are cultured in vitro(italic) cannot reproduce in patients' bodies and have very short life length.(具体的な時間を教えてください) <br> Culturing immune cells in vitro(italic) takes time.(具体的な時間を教えてください) <br> (Concerns about effects on a patient's natural immune system.(実際に問題としてあるか調べる)) <br>The first problem of a irreproducibility can be solves using stem cells such as iPS cells (induced pluripotency stem cells) by stimulating the differentiation to the specific T lymphocytes. However, establishment of the stem cells and differentiation to T-cells in vitro(italic) are troublesome and time-costly as the treatment is patient-specific and the differentiated T-cells are fragile. <br> <br> <h1 class="title"><a name="background">&nbsp;Motivation</a></h1> <br> <font style="font-size:30px;">"Let’s design a self moving vessel!"</font> <br> <p class="paragraph">In order to overcome the pre-stated problem, we decided to build a vessel which moves by not only diffusion but also its internal force; like a ship swims around in the sea by its motor.</p> <br> <font style="font-size:30px;">"But how can we move a vessel?"</font> <br> <p class="paragraph">Facing this difficult problem, we believed we can get an idea from an actual cell in a human body. A dendritic cell, an antigen-presenting cell of the mammalian immune system, moves in a body by migration. The cell has spines which are small actin-rich protrusions; by remodeling (polymerizing and depolymerizing) actin filaments inside, it can change shape and migrate.</p> <p class="paragraph">So that is it! We planned to develop an actin-like monomer (named “Motor-Monomer”) that polymerizes on one end and depolymerizes on the other end to allow mobilization, just as actin filaments in dendritic cells do. We put the Motor-Monomers into a liposome which the Receptor was connected. This Receptor recognizes the outside signal and emits the Polymerization Initiator so that the Motor-Monomers grow to be the Motor-Polymer and a liposome starts patrolling in a body.</p> <p class="paragraph">As we modeled this polymerizing-in-a-liposome system on a dendritic immune cell, we named it "Polymeric and Liposomal Immune Cell (PoLICe)."</p>
