Investigating the potential link between lunar cycle and multiple sclerosis relapses: a call for further studies.

Multiple sclerosis (MS) is a debilitating disease that causes inflammation of the central nervous system, resulting in myelin damage and axon degeneration. Although the cause of MS remains unknown, various factors such as sex, latitude, sun exposure, serum vitamin D levels, Epstein Barr Virus infection, diet, microbiota and ethnicity are being studied for their potential roles in the development of the disease. While chronobiological factors such as circadian rhythm and seasonality have been explored for their potential influence on the onset, exacerbation, and/or relapses of MS, the potential influence of the lunar cycle on MS has yet to be studied.

Sedentary behavior, exercise and COVID-19: immune and metabolic implications in obesity and its comorbidities.

Many reports showed a dramatic decrease in the levels of physical activity during the current pandemic of SARS-CoV-2. This has substantial immune and metabolic implications, especially in those at risk or with metabolic diseases including individuals with obesity and Type 2 diabetes. In this study we discussed the route from physical inactivity to immune and metabolic aberrancies; focusing on how insulin resistance could represent an adaptive mechanism to the low physical activity levels and on how such an adaptive mechanism could shift to a pathognomonic feature of metabolic diseases, creating a vicious circle of immune and metabolic aberrancies.

Dynamics of SARS-CoV-2 infection model with two modes of transmission and immune response.

In this paper, we propose a new within-host model which describes the interactions between SARS-CoV-2, host pulmonary epithelial cells and cytotoxic T lymphocyte (CTL) cells. Furthermore, the proposed model takes into account the lytic and nonlytic immune responses and also incorporates both modes of transmission that are the virus-to-cell infection through extracellular environment and the cell-to-cell transmission via virological synapses. The well-posedness of the model as well as the existence of equilibria are established rigorously.

HLA-D and PLA2R1 risk alleles associate with recurrent primary membranous nephropathy in kidney transplant recipients.

Recurrence of primary membranous nephropathy after transplantation occurs in up to 44% of patients and is driven by PLA2R antibody. Here, we asked whether genetic determinants could improve risk prediction. First, we sequenced PLA2R1 and HLA-D loci in 248 patients with primary membranous nephropathy and identified two independent single nucleotide polymorphisms (SNPs) at risk for primary membranous nephropathy at each locus.
