Summary

The advent of biopharmaceuticals in current medicine brought enormous benefits to the treatment of life-threatening human diseases (e.g., cancer, diabetes and neurodegenerative disorders), and improved the well-being of many people worldwide. The global portfolio of these therapeutic products include proteins and antibodies, nucleic acids, and cell-based products, and continues to expand at a rapid pace - approvals in the period 2015-2018 essentially double the typical five-yearly historical approval pace (G. Walsh, Nat. Biotechnol., 36:1136-1145, 2018) -, representing a significant share of the entire market of pharmaceuticals.

Innovation in the (bio)pharmaceutical industry has been driven towards the development of cost-effective manufacturing processes, envisaging the delivery of products in high quantity, with superior quality (purity), and high specificity, with the ultimate goal of benefiting patients. Progress in this direction have resulted from the application of novel technologies in the upstream stage (high-throughput, single-use devices, statistical optimization of media and fermentation conditions, QbD, and continuous processing), while at the downstream level, chromatography has evolved through the development of new resins and ligands, coupled with advances in process modelling, operating and control strategies.

An emerging trend is the application of alternative solvents such as ionic liquids and deep eutectic solvents, in which their structure and physicochemical properties can be tuned to address unmet needs in (bio)pharmaceutical research. These compounds may be derived from natural and reneawable sources and hold great promise in the development of efficient, sustainable and cost-effective biopharmaceuticals purification processes.

This Entry Collection aims to provide the latest progresses achieved in pharmaceuticals bioprocessing. We welcome submissions of original research, comprehensive reviews and perspectives, including, but not limited, to the following fields:

- Upstream processing (genetic engineering, systems biology, difficult-to-express proteins, expression conditions, Quality by Design approaches, process analytical technologies);

One Health Tomato Probiotics
Based on the literature and knowledge on the “One Health” concept, a new term for probiotics: “One Health probiotics”, beneficial for the unity of people, animals, and the environment, is suggested. Strains of Lactiplantibacillus plantarum, having an ability to ferment a broad spectrum of plant carbohydrates, probiotic effects in human, and animal health, as well as being found in dairy products, vegetables, sauerkraut, pickles, some cheeses, fermented sausages, fish products, and rhizospheric soil, might be suggested as one of the probable candidates for “One Health” probiotics (beneficial for the unity of people, animals, and the environment) for the utilization in agriculture, food processing, and healthcare.

Applications of Moringa oleifera
Moringa oleifera Lam. (Moringaceae) is one of the most essential medicinal plants primarily found in the rainforest area and forest ecosystem, but is now well-adapted in an organized cultivation system. Moringa oleifera (M. oleifera) is well-known as Drumstick tree, Moringa kai, color, Marengo, Moringe, mulangay, Sahjan, and Sajna, which are its native names commonly used. It has nourishing, beneficial, and preventive effects when taken as food and has an extensive scope of high restorative properties with huge dietary benefits. Different parts of the M. oleifera plants, such as leaves, flowers, fruits, seeds, and roots, contain a significant amount of protein, ß-carotene, amino acids, important minerals, and various phenolic compounds. Because of its multifarious health benefits for its therapeutic value, it is considered an essential plant. The plant is found to be blessed with several medicinal characteristics such as antitumor, anti-inflammatory, antiulcer, antipyretic, antiepileptic, antispasmodic, diuretic, antihypertensive, antidiabetic, cholesterol-level down, cell reinforcement, and hepatoprotective. Moreover, it is used traditionally in the local curative system against cardiac problems, and the antifungal properties are efficiently utilized for the treatment of a wide range of ailments.

Secondary Metabolites Isolated from Chilean Marine Algae
Chile is in the extreme southwestern part of America, and it has an extreme length, of approximately 4300 km that increases to 8000 km considering the Chilean Antarctic Territory. Despite the large extent of its coastal territory and the diversity of geographic environments and climates associated with Chilean coasts, the research on marine resources in Chile has been rather scarce.

Microfluidics for 3D Cell and Tissue Cultures
Traditional cell cultures are performed in two-dimensional (2D) systems such as Petri dishes, multiwell plates or flasks. However, they cannot realistically mimic the morphophysiological complexity of the original three-dimensional (3D) in vivo environment from which the cells of specific lines originate. Without opposing animal experimentation but promoting its responsible application, the development of alternative cell culture systems tries to ensure compliance with the 3R principles. Reduction (reduction in the animals used for in vivo tests), Refinement (experimental design optimization to limit stress and affliction to laboratory animals) and Replacement (total or partial replacement of animal testing with alternative valid methods) are increasingly desired and strongly recommended as fundamental ethical aspects in the use of animals in scientific experiments.

Lymphatic Tissue Bioengineering based on Stem Cells
Lymphedema is characterized by progressive and chronic tissue swelling and inflammation from local accumulation of interstitial fluid due to lymphatic injury or dysfunction. It is a debilitating condition that significantly impacts a patient’s quality of life, and has limited treatment options. With better understanding of the molecular mechanisms and pathophysiology of lymphedema and advances in tissue engineering technologies, lymphatic tissue bioengineering and regeneration have emerged as a potential therapeutic option for postsurgical lymphedema. Various strategies involving stem cells, lymphangiogenic factors, bioengineered matrices and mechanical stimuli allow more precisely controlled regeneration of lymphatic tissue at the site of lymphedema without subjecting patients to complications or iatrogenic injuries associated with surgeries.

Natural Products against Breast Cancer
Breast cancer (BC) is the second leading cause of death among women, and it has become a global health issue due to the increasing number of cases. Different treatment options, including radiotherapy, surgery, chemotherapy and anti-estrogen therapy, aromatase inhibitors, anti-angiogenesis drugs, and anthracyclines, are available for BC treatment. However, due to its high occurrence and disease progression, effective therapeutic options for metastatic BC are still lacking. Considering this scenario, there is an urgent need for an effective therapeutic strategy to meet the current challenges of BC. Natural products have been screened as anticancer agents as they are cost-effective, possess low toxicity and fewer side effects, and are considered alternative therapeutic options for BC therapy. Natural products showed anticancer activities against BC through the inhibition of angiogenesis, cell migrations, proliferations, and tumor growth; cell cycle arrest by inducing apoptosis and cell death, the downstream regulation of signaling pathways (such as Notch, NF-κB, PI3K/Akt/mTOR, MAPK/ERK, and NFAT-MDM2), and the regulation of EMT processes. Natural products also acted synergistically to overcome the drug resistance issue, thus improving their efficacy as an emerging therapeutic option for BC therapy.

Potential Therapeutic Targets for TNBC Therapy
TNBC exhibits high heterogeneity, which is the major limitation of chemotherapy. Also, TNBC is regarded as an aggressive type of cancer that grows faster and metastasizes to the brain and visceral organs, providing a much shorter average survival time of about 12 months to patients suffering from advanced TNBC. Therefore, the recognition of definitive targets, for providing efficient treatment against TNBC, becomes a noteworthy task.

Neoantigen-Derived Cancer Vaccines
Cancers are driven by genetic instabilities that rapidly accumulate somatic mutations and eventually alter cell properties. Cancer immunotherapy has achieved multiple clinical benefits and has become an indispensable component of cancer treatment. Targeting tumor-specific antigens, also known as neoantigens, plays a crucial role in cancer immunotherapy. T cells of adaptive immunity that recognize neoantigens, but do not induce unwanted off-target effects, have demonstrated high efficacy and low side effects in cancer immunotherapy.
