Assessment of the biological activity of fish muscle protein hydrolysates using in vitro model systems.

Food Chem 2021 Apr 20;359:129852. Epub 2021 Apr 20.

School of Food and Nutritional Science, University College Cork, T12 YN60 Cork, Ireland. Electronic address:

The generation of biologically active fish protein hydrolysates (FPH) is a useful technique to produce value-added products with potential application in the functional food and nutraceutical industries. Fish muscle is an attractive substrate for the production of protein hydrolysates due to its rich protein content, containing 15-25% of total fish protein. This paper reviews the production of protein hydrolysates from fish muscle, most commonly via enzymatic hydrolysis, and their subsequent bioactivities including anti-obesity, immunomodulatory, antioxidant, angiotensin I-converting enzyme (ACE)-inhibitory, anti-microbial, and anti-cancer activities as measured by in vitro testing methods.

AhR Ligands Modulate the Differentiation of Innate Lymphoid Cells and T Helper Cell Subsets That Control the Severity of a Pulmonary Fungal Infection.

Front Immunol 2021 16;12:630938. Epub 2021 Apr 16.

Department of Immunology, Institute of Biomedical Sciences, University of São Paulo, São Paulo, Brazil.

In agreement with other fungal infections, immunoprotection in pulmonary paracoccidioidomycosis (PCM) is mediated by Th1/Th17 cells whereas disease progression by prevalent Th2/Th9 immunity. Treg cells play a dual role, suppressing immunity but also controlling excessive tissue inflammation. Our recent studies have demonstrated that the enzyme indoleamine 2,3 dioxygenase (IDO) and the transcription factor aryl hydrocarbon receptor (AhR) play an important role in the immunoregulation of PCM.

Endocrine and immunomodulatory effects of social isolation and loneliness across adulthood.

Psychoneuroendocrinology 2021 Mar 8;128:105194. Epub 2021 Mar 8.

Department of Psychology, Wayne State University, USA.

Experimental and observational evidence agreed on two interconnected biological mechanisms responsible for the links between social isolation/loneliness and health: alterations in the activity of the hypothalamic-pituitary-adrenal (HPA) axis and compromised functioning of the innate immune system. However, most existing studies did not consider the simultaneous impact of social isolation and loneliness on biological outcomes. Further, they only assessed one biological outcome at a time and did not test any moderation by age, despite empirical and theoretical evidence supporting the plausibility of this hypothesis.

Degraded sulfated polysaccharide relieves ovalbumin-induced food allergic response by restoring the balance of T helper cell differentiation.

Food Funct 2021 Apr 30. Epub 2021 Apr 30.

Allergy Department, State Key Laboratory of Complex Severe and Rare Diseases, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100730, China.

We previously described that Porphyra haitanensis sulfated polysaccharide (PHSP) maintains the balance of pro-inflammation and immunosuppression. However, it is unclear whether degraded PHSP (DPHSP) still shows the immunomodulatory activity. Here, we degraded PHSP by four different methods alone or combined in pairs, and the results showed that the molecular weight and viscosity of DPHSP were significantly decreased, while the main chemical bonds and functional structure were consistent with those of PHSP.

Interplay of Opposing Effects of the WNT/β-Catenin Pathway and PPARγ and Implications for SARS-CoV2 Treatment.

Front Immunol 2021 13;12:666693. Epub 2021 Apr 13.

University Hospital Center (CHU) Amiens Picardie, University of Picardie Jules Verne (UPJV), Amiens, France.

The Coronavirus disease 2019 (COVID-19), caused by the novel coronavirus SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), has quickly reached pandemic proportions. Cytokine profiles observed in COVID-19 patients have revealed increased levels of IL-1β, IL-2, IL-6, and TNF-α and increased NF-κB pathway activity. Recent evidence has shown that the upregulation of the WNT/β-catenin pathway is associated with inflammation, resulting in a cytokine storm in ARDS (acute respire distress syndrome) and especially in COVID-19 patients.

Therapeutic Potential of Alpha-1 Antitrypsin in Type 1 and Type 2 Diabetes Mellitus.

Medicina (Kaunas) 2021 Apr 20;57(4). Epub 2021 Apr 20.

Department of Medicine, State University of New York Downstate Health Sciences University, Brooklyn, NY 11203, USA.

Alpha-1 antitrypsin (AAT) has established anti-inflammatory and immunomodulatory effects in chronic obstructive pulmonary disease but there is increasing evidence of its role in other inflammatory and immune-mediated conditions, like diabetes mellitus (DM). AAT activity is altered in both developing and established type 1 diabetes mellitus (T1DM) as well in established type 2 DM (T2DM). Augmentation therapy with AAT appears to favorably impact T1DM development in mice models and to affect β-cell function and inflammation in humans with T1DM. Read More

Microparticles and Nanoparticles from Plants-The Benefits of Bioencapsulation.

Vaccines (Basel) 2021 Apr 11;9(4). Epub 2021 Apr 11.

Institute of Plant Biotechnology and Cell Biology, Department of Applied Genetics and Cell Biology, University of Natural Resources and Life Sciences, 1190 Vienna, Austria.

The efficacy of drugs and vaccines depends on their stability and ability to interact with their targets in vivo. Many drugs benefit from encapsulation, which protects them from harsh conditions and allows targeted delivery and controlled release. Although many encapsulation methods are inexpensive, such as the formulation of tablets for oral delivery, others require complex procedures that add significantly to production costs and require low-temperature transport and storage, making them inaccessible in developing countries.
