Optogenetics technology is an emerging tool for researchers to control cellular function. Over the past several years, it has had a strong impact in a variety of applications, including but not limited to: cell signaling and dynamics, developmental biology, microbial transcription, cancer signaling and drug response, control of T-cell receptor signaling, and materials science.

The 4th Optogenetic Technologies and Applications Conference, organized by the Society for Biological Engineering (SBE), will bring together communities of researchers who are either working in optogenetics or who stand to benefit from utilizing optogenetic tools for various biological applications. This conference provides unique value to realizing the potential of the field across a variety of disciplines.

We recently caught up with Deniz Kent, PhD, Co-Founder and CEO at Prolific Machines, to discuss how the company is using optogenetics tools in commercial applications.

Can we start with your perspective on the state of biomanufacturing?

I think it鈥檚 remarkable what has been achieved, but I also believe there鈥檚 untapped potential. Biology could do much more than it鈥檚 currently doing and it could also do the things that it鈥檚 currently doing, better.

For the last few decades, biomanufacturing has relied on molecules to control cells. These molecules tend to be in one of two categories: proteins or chemicals. They鈥檙e mixed up, kind of like cocktails, and added to cells. Different cocktails do different things. This has worked reasonably well and has led to the modern biotech industry. However, I believe there鈥檚 a lot more that cells could do that we currently aren鈥檛 using them for. We need a better toolkit to control cells that move away from molecular to non-molecular inputs. 

What is Prolific Machines doing to solve these issues?

Prolific Machines is building a new toolkit to control cells using light. Light systematically solves the myriad challenges created by our reliance on molecular inputs: high costs, sterility issues, yield limitations, lack of reproducibility, irreversibility, delayed responsiveness, inability to optimize, and imprecise control 鈥 especially on the time and space axis.

Light can solve these problems because it鈥檚 the cheapest possible input into biology, and it鈥檚 also extremely controllable. It allows for very precise control based on where and when you shine it and the intensity with which you shine it. The temporal control provides significant yield advantages, and the space access allows for precise patterning. It's also extremely reproducible, sterile, and easy to optimize.

The optimizability piece is really important, given the closed-loop control, which is only possible because of light. Prolific is building the world鈥檚 first tools that will be able to truly control subcellular biology selectively. We have tools that can turn on or off cell receptors, activate a cytoplasmic enzyme, cascade precise gene editing, dynamically control protein production, and turn one type of cell into another type of cell. 

Based on these tools, how exactly does Prolific Machines use light? 

We currently offer four tools to our customers: OptoReceptor activates receptors, OptoMeta tunes metabolism, OptoPro controls protein production, and OptoDiff turns one type of cell into another type of cell. 

Each of these requires a specific engineering and light patterning scheme, and this is really the magic of Prolific. It鈥檚 not just that we use light, it鈥檚 the specific light patterns we employ to enable specific applications, and how we change these light patterns throughout a bioproduction run to precisely control cellular behavior and output. We can tune our signaling to support the cells鈥 evolving needs at different points, allowing for unparalleled control. We can also optimize these actions over time using proprietary AI, adding further fine tuning capabilities to our process.

Where is Prolific Machine鈥檚 technology being applied?

There are two industries we鈥檙e currently having active conversations about with prospective partners. One is advanced nutrition. We鈥檙e speaking to meat and dairy companies about using our bovine cell lines to support the production of high-value nutritional proteins and cultivated products. There鈥檚 so much you can do with our tools here.

The second is our biomanufacturing platform. We鈥檙e speaking with biopharmaceutical companies and CDMOs about using our light-inducible switches in CHO cell lines to improve and enable production of therapeutic proteins with key advantages in difficult-to-express protein production. 

We recently received a grant from the Bill & Melinda Gates Foundation to develop an antibody therapeutics platform to produce more affordable monoclonal antibodies, to increase access to these life-saving drugs in vulnerable populations in low- and middle- income countries. There are also several future opportunities on our radar, including tissue and organ engineering, cell therapy, and many more. 

How do you work with these partners?

We have designed our photomolecular platform to be very easy for partners to use. It鈥檚 comprised of three parts: genetic tools, hardware, and software, providing an easy-to-integrate infrastructure. 

Our platform is cell line agnostic, and we offer high performance cell lines (bovine and CHO) partners can use, or they can choose to use their own. The hardware is plug and play with a partner鈥檚 existing process, and the software is embedded into the hardware to signal, sense, and optimize.  With the AI component of our software, we are teaching machines how to control and grow cells so that eventually they鈥檒l be able to run autonomously. 

Together, our platform not only solves challenges created from molecular inputs, but innovates on existing CapEx, provides higher yields, and builds autonomy into how you run these bioreactors. 

I think the combination of those things will take biotech from being something that doesn鈥檛 necessarily and explicitly touch that many people鈥檚 lives, to biotech being used everywhere and touching everything.
