Directed evolution can enable engineering of biological systems with minimal knowledge of their underlying sequence-to-function relationships. A typical directed evolution process consists of iterative rounds of mutagenesis and selection that are designed to steer changes in a biological system (e.g.

Multidrug-resistant tuberculosis (MDR-TB) patients are treated with a standardised, short World Health Organization (WHO) regimen which includes clofazimine (CFZ) and bedaquiline (BDQ) antibiotics. These two antibiotics lead to the development of QT prolongation in patients, inhibiting potassium (K) uptake by targeting the voltage-gated K (Kv)11.1 (hERG) channel of the cardiomyocytes (CMs).

Article Synopsis
  • The study investigates the effects of SARS-CoV-2 on people living with HIV (PLWH) in Africa, focusing on T-cell variations and inflammatory profiles during COVID-19 hospitalization.
  • Among 174 patients studied, 21% were PLWH, who were generally younger and more likely to be female compared to those without HIV.
  • Findings reveal that PLWH had unique T-cell characteristics and inflammatory markers, indicating differing immune responses depending on their CD4+ T-cell counts, suggesting a need for tailored treatment approaches.

Antiretroviral therapy (ART) has reduced the mortality and morbidity associated with HIV. However, irrespective of treatment, people living with HIV remain at a higher risk of developing non-AIDS-associated diseases. In 2019, the World Health Organization recommended the transition from efavirenz (EFV)- to dolutegravir (DTG)-based ART.

Mathematical modeling is indispensable in synthetic biology but remains underutilized. Tackling problems, from optimizing gene networks to simulating intracellular dynamics, can be facilitated by the ever-growing body of modeling approaches, be they mechanistic, stochastic, data-driven, or AI-enabled. Thanks to progress in the AI community, robust frameworks have emerged to enable researchers to access complex computational hardware and compilation.
