Probiotic Lactobacillus kefiri prevents endotoxin-induced preterm birth and stillbirth in mice.

Reproduction 2021 Apr 1. Epub 2021 Apr 1.

F Jensen, Immunology of Pregnancy Laboratory, CEFYBO, BUENOS AIRES, Argentina.

Preterm birth (PTB), defined as birth occurring before 37 weeks of pregnancy, affects 5-18% of pregnancies and is the leading cause of neonatal morbidity and mortality worldwide. Although PTB is considered a syndrome, infection-induced inflammation accounts up to 50% of all cases. Despite the effort to reduce the incidence of PTB, it continues rising worldwide and current approaches for preventing or treating PTB are largely unsatisfactory. Read More

PCSK9 Functions in Atherosclerosis Are Not Limited to Plasmatic LDL-Cholesterol Regulation.

Front Cardiovasc Med 2021 23;8:639727. Epub 2021 Mar 23.

Cardiovascular Program ICCC, IR-Hospital de la Santa Creu i Sant Pau, IIB-Sant Pau, Barcelona, Spain.

The relevance of PCSK9 in atherosclerosis progression is demonstrated by the benefits observed in patients that have followed PCSK9-targeted therapies. The impact of these therapies is attributed to the plasma lipid-lowering effect induced when LDLR hepatic expression levels are recovered after the suppression of soluble PCSK9. Different studies show that PCSK9 is involved in other mechanisms that take place at different stages during atherosclerosis development. Read More

Arthritis Res Ther 2021 Apr 8;23(1):105. Epub 2021 Apr 8.

Shirahama Foundation for Health and Welfare, Search Institute for Bone and Arthritis Disease (SINBAD), Nishimuro-gun, Shirahama-cho 1447, Wakayama, 649-2211, Japan.

Background: The dietary inflammatory index (DII®), a quantitative measure of the inflammatory potential of daily food and nutrient intake, and associations between a variety of health outcomes have been reported. However, the association between DII score and disease activity of rheumatoid arthritis (RA) is unclear. Therefore, this study was designed to test whether higher DII score contributes to disease activity and as a corollary, whether reducing DII score helps to achieve or maintain low disease activity or remission in patients with RA.

Glucocorticoids: Dr. Jekyll and Mr. Hyde of Hippocampal Neuroinflammation.

Biochemistry (Mosc) 2021 Feb;86(2):156-167

Institute of Higher Nervous Activity and Neurophysiology, Russian Academy of Sciences, Moscow, 117485, Russia.

Glucocorticoids (GCs) are an important component of adaptive response of an organism to stressogenic stimuli, a typical stress response being accompanied by elevation of GC levels in blood. Anti-inflammatory effects of GCs are widely used in clinical practice, while pro-inflammatory effects of GCs are believed to underlie neurodegeneration. This is particularly critical for the hippocampus, brain region controlling both cognitive function and emotions/affective behavior, and selectively vulnerable to neuroinflammation and neurodegeneration.

Dysregulation of metallothionein and zinc aggravates periodontal diseases.

J Trace Elem Med Biol 2021 Apr 3;66:126754. Epub 2021 Apr 3.

Department of Restorative Dentistry, Faculty of Dentistry, University of Malaya, Kuala Lumpur, 50603, Malaysia.

Background: Periodontitis (PD) is a multifaceted inflammatory disease connected to bacterial infection that results in the destruction of tooth supporting structures and eventually tooth loss. Given their involvement in infection and inflammation, both metallothionein (MT) and zinc (Zn) might play vital roles in the development and progression of PD. More specifically, both MT and Zn are heavily involved in regulating immune functions, controlling bacterial infection, balancing inflammatory responses, and reducing oxidative stress, all of which are associated with the pathogenesis of PD.

Ellagitannins from Rosa roxburghii suppress poly(I:C)-induced IL-8 production in human keratinocytes.

J Nat Med 2021 Apr 8. Epub 2021 Apr 8.

Medical Science Division, United Graduate School of Drug Discovery and Medical Information Sciences, Gifu University, 1-1 Yanagido, Gifu City, Gifu, 501-1194, Japan.

The anti-inflammatory effects of a 50% aqueous extract of Rosa roxburghii fruit (RRFE) and two ellagitannins (strictinin and casuarictin) isolated from the RRFE were evaluated in a cell model of skin inflammation induced by self-RNA released from epidermal cells damaged by UV ray (UVR) irradiation. The RRFE inhibited interleukin-8 (IL-8) mRNA expression in normal human epidermal keratinocytes (NHEKs) stimulated with polyinosinic:polycytidylic acid (poly(I:C)), a ligand of toll-like receptor-3 (TLR-3). The plant-derived anti-inflammatory agents, dipotassium glycyrrhizinate (GK2) and allantoin, had no influence on the IL-8 expression. Read More

C-Phycocyanin-derived Phycocyanobilin as a Potential Nutraceutical Approach for Major Neurodegenerative Disorders and COVID-19-induced Damage to the Nervous System.

Curr Neuropharmacol 2021 Apr 8. Epub 2021 Apr 8.

Catalytic Longevity Foundation, 811 B Nahant Ct. San Diego, CA 92019. United States.

The edible cyanobacterium Spirulina platensis and its chief biliprotein C-Phycocyanin have shown protective activity in animal models of diverse human health diseases, often reflecting antioxidant and anti-inflammatory effects. The beneficial effects of C-Phycocyanin seem likely to be primarily attributable to its covalently attached chromophore Phycocyanobilin (PCB). Within cells, biliverdin is generated from free heme and it is subsequently reduced to bilirubin. Read More

Sustainable Drug Discovery of Multi-Target-Directed Ligands for Alzheimer's Disease.

J Med Chem 2021 Apr 8. Epub 2021 Apr 8.

Department of Pharmacy and Biotechnology, Alma Mater Studiorum - University of Bologna, Via Belmeloro 6, 40126 Bologna, Italy.

The multifactorial nature of Alzheimer's disease (AD) is a reason for the lack of effective drugs as well as a basis for the development of "multi-target-directed ligands" (MTDLs). As cases increase in developing countries, there is a need of new drugs that are not only effective but also accessible. With this motivation, we report the first sustainable MTDLs, derived from cashew nutshell liquid (CNSL), an inexpensive food waste with anti-inflammatory properties. Read More

Evaluation of single and combined effects of two pharmaceuticals on the marine gastropod Phorcus lineatus enzymatic activity under two different exposure periods.

Ecotoxicology 2021 Apr 7. Epub 2021 Apr 7.

Departamento de Biologia, Universidade de Aveiro, Campus de Santiago, 3810-193, Aveiro, Portugal.

Pharmaceutical drugs are among the most used chemicals for human and veterinary medicines, aquaculture and agriculture. Pharmaceuticals are environmentally persistent, biologically active molecules, thereby having the potential to exert biological effects on non-target species. Among the most used pharmaceuticals, one may find salicylic acid (SA), a non-steroid anti-inflammatory drug (NSAID) that acts by inhibiting the enzymes cyclooxigenases; it is also possible to identify acetazolamide (ACZ), a diuretic that acts by inhibiting the activity of carbonic anhydrase (CA).

Front Oncol 2021 22;11:644416. Epub 2021 Mar 22.

Department of Gastroenterology, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, China.

Background: Hepatocellular carcinoma (HCC) is a highly heterogeneous disease, which makes the prognostic prediction challenging. As part of the active cross-talk between the tumor and the host, inflammatory response in the tumor or its microenvironment could affect prognosis. However, the prognostic value of inflammatory response-related genes in HCC remains to be further elucidated. Read More
