Cyclic adenosine 3’,5’-monophosphate (cAMP) is a versatile secondary messenger that communicates with Guanine Nucleotide Exchange Factor (EPAC) to transfer cellular signaling and regulates numerous physiological conditions. Early studies focused on measuring this communication is considered as crucial in GPCR ligand-mediated EPAC activation, where bioluminescence resonance energy transfer (BRET) sensor has been widely used to study the cAMP level in living cells. However, a BRET sensor pairing with the best brightness and photostability for detecting low levels of cAMP in single and whole-cell populations has yet to be developed. Here, we constructed a novel BRET-based cAMP biosensor with Rluc-Epac-Citrine2. A molecular communication study revealed a significant change of over 100° in the phi value for the residues Thr253, Val259, and Thr260 in the presence of cAMP, leading to strong cAMP-Epac-induced dynamics in the ternary complex. Spectrum scanning, luminescence, and fluorescence emission studies on glioblastoma multiforme (GBM) cells demonstrated closer proximity between donor and acceptor, ensuring the cAMP sensor’s activity. This sensor detects changes in endogenous cAMP levels, and the observed BRET signal can be enhanced by increasing the concentration of the substrate, coelenterazine. The sensor also efficiently detects the communication between cAMP and EPAC in live GBM cells over time. We used this sensor to assess the activation of GPR17, a potential biomarker for GBM. The activation of MDL 29,951, a GPR17 agonist, supports the sensor’s ability to detect Gi-coupled protein activation. This study also shows the feasibility of sensor readouts using inexpensive instrumentation such as plate readers and image systems. Overall, this study sheds new light on detecting cAMP communication with EPAC and GPR17 ligand-mediated EPAC in GBM cells, potentially aiding the development of precision therapies.

In this paper, we propose an analysis of the transmission success probability in a Förster resonance energy transfer (FRET)-based molecular communication system. FRET is an energy transmission process between molecules in close proximity without radiation of a photon. Since FRET has low dependency on environmental factors and a relatively wide transmission range, it has become a promising means of propagation in molecular communication. However, the limited availability of current research in the literature hampers comprehensive understanding of FRET capabilities in the context of wireless communication in general and molecular communication specifically. In this paper, we model a FRET-based communication system with relays and analyze its channel characteristics. We derive a theoretical expression for the successful transmission probability of the system under on-off keying modulation and the corresponding system capacity. Our analysis shows that performance of the proposed FRET system is influenced by parameters that include the FRET rate, the intrinsic fluorescence rate, and symbol duration. Furthermore, our analysis maintains a high level of accuracy, regardless of whether the relays share the same FRET rate or possess different FRET rates. Via simulations our analysis is verified in various environments.

Internet of Things (IoT) translates the physical world into a cyber form using wireless sensors. However, these sensors often lack longevity due to their energy-constrained batteries. This limitation is particularly critical for the Internet of Bio-Nano Things (IoBNT), in which sensors usually operate within an organism with minimum opportunities for replenishment. Thus, adopting energy-efficient strategies is vital to maximize the lifetime of such sensors and ensure the reliable execution of associated applications. To address this, this letter proposes an event-driven, time-adaptive transmission scheme based on the Kullback-Leibler (KL) distance. Specifically, the KL distance is used to measure the worth of transmitting the current sensor reading, enabling the sensor to decide whether to transmit in that sampling period, thereby saving energy and extending its lifetime. Furthermore, we identify the operational regions for sensors, namely safe, unsafe, and action, depending on application-specific parameters. The design and implementation of the required circuitry are also discussed, considering the unique constraints of the IoBNT. Performance evaluation validates that the KL distance improves sensor lifetime with an acceptable information loss.

Evolutionary developmental biology, biomedicine, neuroscience, and many aspects of the social sciences are impacted by insight into forces that facilitate the merging of active subunits into an emergent collective. The dynamics of interaction between agents are often studied in game theory, such as the popular Prisoner’s Dilemma (PD) paradigm, but the impact of these models on higher scales of organization, and their contributions to questions of how agents distinguish borders between themselves and the outside world, are not clear. Here we applied a spatialized, iterated PD model to understand the dynamics of the formation of large-scale tissues (colonies that act as one) out of single cell agents. In particular, we broke a standard assumption of PD: instead of a fixed number of players which can Cooperate or Defect on each round, we let the borders of individuality remain fluid, enabling agents to also Merge or Split. The consequences of enabling agents’ actions to change the number of agents in the world result in non-linear dynamics that are not known in advance: would higher-level (composite) individuals emerge? We characterized changes in collective formation as a function of memory size of the subunits. Our results show that when the number of agents is determined by the agents’ behavior, PD dynamics favor multicellularity, including the emergence of structured cell-groups, eventually leading to one single fully-merged tissue. These larger agents were found to have higher causal emergence than smaller ones. Moreover, we observed different spatial distributions of merged connectivity vs. of similar behavioral propensities, revealing that rich but distinct structures can coexist at the level of physical structure and the space of behavioral propensities. These dynamics raise a number of interesting and deep questions about decision-making in a self-modifying system that transitions from a metabolic to a morphological problem space, and how collective intelligences emerge, scale, and pattern.

Diabetes mellitus is a global health crisis characterized by poor blood sugar regulation, impacting millions of people worldwide and leading to severe complications and mortality. Although Type 1 Diabetes Mellitus (T1DM) has a lower number of cases compared to other forms of diabetes, it is often diagnosed at a young age and requires lifelong exogenous insulin administration. In this paper, we focus on understanding the interaction of insulin and glucose molecules within the subcutaneous layer, which is crucial for blood sugar control in T1DM patients. Specifically, we propose a comprehensive model to characterize the insulin-glucose system within the subcutaneous layer, incorporating a multicellular molecular communication system. We then divide the T1DM system into insulin and glucose subsystems and derive the end-to-end expression for insulin-glucose interaction in the subcutaneous layer. We further validate the insulin-glucose interaction analysis with an agent-based simulator. As effectively managing postprandial glucose levels is crucial for individuals with T1DM to safeguard their overall health and avert short-term and long-term complications, we also derive the optimal insulin administration time based on the derived glucose response via the Lagrange multiplier and gradient descent ascent method. This allows us to explore the impact of different types of insulin and dietary management on blood sugar levels. Simulation results confirm the correctness of our proposed model and the effectiveness of our optimized effective time window for injecting insulin in individuals with T1DM.

This work considers a three-dimensional mobile molecular communication (MC) with intra-body disease spread applications. The communicating devices in the considered mobile MC system are point transmitters and passive spherical receiver nano-machines (NMs) with emitted information-carrying molecules following the Gaussian Brownian motion. These NMs can be used to detect the presence of disease spread and for targeted drug delivery. We propose stochastic diffusivity models for both communicating devices and information-carrying molecules. Using the stochastic diffusivity model and considering initial distance as a reference, we derive the probability density function of the relative distance between the communicating devices. We allocate the time-varying trajectory to the information-carrying molecules moving towards receiver NM and obtain its diffusivity distribution. Through the proposed stochastic diffusivity model, we characterize the mobile MC channel by channel impulse response and derive its statistical mean. We consider the discrete-time statistical channel model at a high inter-symbol interference regime and analyze the channel performance in terms of error analysis and receiver operating characteristics. We also derive the channel capacity for the considered system model. We show the degree of accuracy through root mean square error for the Poisson and Gaussian distribution models. Furthermore, the numerical results are verified through particle-based simulations.

Molecular communication (MC) represents a novel approach to communication that employs nanoengineering and bioengineering technology to establish transient communication links in challenging environments. Deoxyribonucleic acid (DNA) molecular communication can transmit more and faster data than traditional molecular communication. Deoxyribonucleic acid (DNA) has been demonstrated to offer significant advantages over traditional information carriers, including its excellent storage density and structural stability, which renders it an ideal medium for information transmission. It is therefore imperative to investigate methods of increasing the data information density of DNA in order to reduce costs and enhance overall performance. LZW encoding is Lempel-Ziv–Welch encoding which creates a string table with shorter codes representing longer strings. Arithmetic coding is a compression process that involves the continuous refinement of probabilities of the input stream within an interval. A notable drawback of LZW coding is its suboptimal compression efficiency and the presence of data redundancy after dictionary mapping. Conversely, arithmetic coding attains compression efficiency that approaches the Shannon limit. In this study, we propose a novel DNA encoding method which is capable of adaptively generating coding streams in accordance with the characteristics of the stored content. The contribution of this paper is as follows: 1) A bespoke coding dictionary is constructed, which is capable of intelligently generating the corresponding coding stream in accordance with the specific characteristics of the file to be stored. 2) Utilising arithmetic coding techniques, these coding streams are converted into the final DNA sequence by means of compression techniques. Following comprehensive verification, it has been established that the information density of this encoding method is markedly superior to that of the prevailing mainstream encoding schemes.
