当一个信号分子结合到细胞表面的RTKs，两种受体相互结合的过程称为二聚化作用。这个过程会激活细胞的信号转导。Janovjak，格吕施和同事将哺乳动物的RTKs的那些部分与光 - 氧 - 电压传感领域(鉴定黄绿藻的可逆光传感器)结合。在工程化受体中，二聚化步骤和随后的细胞信号转导现在可以通过光随着藻蛋白光感打开和关闭，以及彼此结合。在肿瘤细胞中，工程受体的活化导致细胞形态变化，细胞增殖和基因表达，增加癌症的恶性程度的特性。在血细胞中，活化导致细胞出芽，典型的新血管形成。
RTKs通过光激活二聚化作用调节发育是哺乳动物受体的光激活二聚化作用的*个实例。光控制下的RTK提供了强大的光遗传学的方法来启动细胞信号和操纵细胞的行为。新开发的受体引发癌症和血液中内皮细胞复杂的细胞活动。这些细胞代表根据光控行为的新模型，以及能够用新的方法来确定药物。这与癌细胞的相反，细胞信号转导的不受控制的活化导致恶性肿瘤有关的特征，信号转导的光激活可能拯救退行性疾病的细胞存活和功能。“渐冻症”是运动神经元病的一种，患者逐渐丧失运动机能甚至瘫痪，其中有名的是英国科学家霍金。这种病被认为与神经胶质细胞异常有关，神经胶质细胞可负责维持神经细胞的网络并向神经细胞提供营养。
京都大学教授井上治久率领的研究小组，利用ips细胞制作出可变化为神经胶质细胞的前驱细胞，然后向24只患有渐冻症的实验鼠脊髓各移植了约8万个这种细胞。
结果发现，移植了前驱细胞的24只渐冻症实验鼠的平均生存期为162天，而没有移植的24只实验鼠仅为150天。研究小组说，移植的前驱细胞几乎全部变为神经胶质细胞之一的星形胶质细胞，开始产生维持神经细胞所需的蛋白质，而且这些移植的细胞没有发生癌变。

When a signaling molecule binds to a cell surface RTKs, the two receptors bind to each other as a dimerization. This process activates cell signaling. Janovjak, Gruch and colleagues combined those parts of the mammalian RTKs with the field of photo-oxygen-voltage sensing, a reversible light sensor that identifies Chlorella. In engineered receptors, the dimerization step and subsequent cellular signal transduction can now be turned on and off by light along with the algin protein and bind to each other. In tumor cells, activation of engineered receptors leads to changes in cell morphology, cell proliferation and gene expression, and increases the malignancy of cancers. In blood cells, activation leads to cell budding, typical neovascularization.
RTKs regulate development through photoactivation dimerization as the first instance of photoreactive dimerization of mammalian receptors. RTK under light control provides a powerful method of optogenetics to initiate cellular signaling and manipulate cellular behavior. The newly developed receptors trigger complex cellular activities of cancer and endothelial cells in the blood. These cells represent new models based on photocontrol behavior, as well as being able to identify new drugs with new methods. This is in contrast to cancer cells, where uncontrolled activation of cell signaling leads to malignancy-related features, and photo-activation of signal transduction may rescue the cell survival and function of degenerative diseases. "Asymptomatic" is a kind of motor neuron disease, patients gradually lose motor function or even paralysis, of which the most famous is the British scientist Hawking. The disease is thought to be associated with abnormalities in glial cells, which can be responsible for maintaining the network of nerve cells and providing nutrients to nerve cells.
A team led by Professor Inoue Ishiguro of Kyoto University used ips cells to make precursor cells that could be changed to glial cells. Then, about 80,000 of these 24 cells were transplanted into the spinal cord of 24 experimental mice with gradual freezing frost.
The results showed that the average survival time of 24 mice with asherogenic syndrome transplanted with precursor cells was 162 days compared to only 150 days with 24 mice without transplantation. The team said almost all of the transplanted precursor cells became astrocytes, one of the glial cells, and started producing the proteins needed to sustain the nerve cells, and none of the transplanted cells were cancerous.
