The identification of the SARS-CoV-2 Omicron variant has raised concerns globally, as it may have a higher rate of transmission and a significant number of mutations, potentially impacting the control and treatment of the pandemic. The World Health Organization has designated this variant as a variant of concern and named it Omicron. The transmission method and severity of Omicron have been well defined, but there are still many speculations regarding its origin and infectivity.
The global COVID-19 outbreak has returned with the identification of the SARS-CoV-2 Omicron variant (B.1.1.529) after appearing to be persistently spreading for the more than past two years. In comparison to prior SARS-CoV-2 variants, this new variant revealed a significant amount of mutation. This novel variety may have a greater rate of transmissibility which might impede the effectiveness of current diagnostic equipment as well as vaccination efficacy and also impede immunotherapies (Antibody / monoclonal antibody based). WHO designated B.1.1.529 as a variant of concern on November 26, 2021, identified as Omicron. The Omicron variant transmission method and severity, on the other hand, are well defined. The global spread of Omicron, which has now seized many nations, has resulted in numerous speculations regarding its origin and degree of infectivity. The following sections will go over its potential for transmission, omicron structure, and impact on COVID-19 vaccines, how it is different from delta variant and diagnostics.

IL-24 intrinsically regulates Th17 cell pathogenicity in mice

Christopher Sie, Ravi Kant, Christian Peter, Andreas Muschaweckh, Monika Pfaller, Lucy Nirschl, Helena Dominguez Moreno, Tereza Chadimova, Gildas Lepennetier, Tanja Kuhlmann, Rupert Ollinger, Thomas Engleitner, Roland Rad, Thomas Korn

Summary: Th17 cells have an intrinsic feedback mechanism to control their pathogenicity, involving the production of IL-24 and secretion of IL-10. IL-24 interacts with Grim19 on the inner mitochondrial membrane to promote STAT3 accumulation in the mitochondrial compartment, which serves as a rheostat to regulate nuclear STAT3 activity. This mechanism plays an important role in restricting immunopathology associated with Th17 cells.

Laura Tuomisto, Ravi Kant, Anna-Mariam Kiviranta, Kukka-Maaria Helkioe, Tarja Sironen, Antti Sukura, Rebecca P. Wilkes, Kristel Kegler

Summary: This case report describes a case of granulomatous colitis (GC) associated with adherent-invasive Escherichia coli (AIEC) that spread to various organs in a 10-year-old, male Sphynx cat. The cat initially experienced diarrhea and sudden blindness before rapidly progressing to ataxia, seizures, and death. Inflammation consistent with granulomatous inflammation was found in all affected organs, and the presence of AIEC within enterocytes and infiltrating macrophages was confirmed.

Summary: The authors describe a small antibody-like protein, TriSb92, that can prevent infection by diverse SARS-CoV-2 variants. In cell culture and mice, intranasal treatment with TriSb92 before or shortly after exposure to the virus showed protective effects. This highly manufacturable and stable trimeric antibody-mimetic has the potential to be used as a nasal spray for protecting susceptible individuals from SARS-CoV-2 infection.

Summary: Weissella strains are commonly found in spontaneously fermented foods and can improve the sensory properties and nutritional values of the products due to their ability to produce lactic acid, functional exopolysaccharides, and probiotic traits. However, some Weissella species have been associated with human and animal diseases. Genomic analyses are crucial in order to fully understand individual Weissella species.

Eccard, Jasmin Firozpoor, Christian Imholt, Joanna Nowicka, Aleksander Goll, Nathan Ranc, Guillaume Castel, Nathalie Charbonnel, Tarja Sironen

Summary: We conducted serologic surveillance on 1,237 wild rodents and small mammals in Europe to assess exposure to SARS-CoV-2. Results showed that all samples tested negative, except for one possible exception. Despite the potential for human-to-rodent spillover, there is currently no evidence of widespread circulation of SARS-CoV-2 in rodent populations.

C-Peptide-Positive, Autoantibody-Negative Type 1 Diabetes Mellitus

Rachel M. Fenner, Samantha Bookbinder, Ravi Kant, Brewer Eberly

Summary: This article describes a case of a female patient who was previously diagnosed with C-peptide positive type 1 diabetes mellitus and had been controlling the disease with insulin. Ten years later, her C-peptide levels increased along with other markers associated with type 1 diabetes, suggesting the possibility of pancreatic beta cell regeneration or increased function. This finding challenges the commonly accepted belief that individuals with type 1 diabetes lose all function of pancreatic beta cells.

Vera Analise Schommer, Mateus Torres Nazari, Flavia Melara, Julia Catiane Arenhart Braun, Alan Rempel, Lara Franco dos Santos, Valdecir Ferrari, Luciane Maria Colla, Aline Dettmer, Jeferson Steffanello Piccin

Summary: This review introduces the techniques and mechanisms of bacteria immobilization on biochar, as well as its applications in bioremediation and agriculture. The immobilization characteristics of biochar depend on pyrolysis methods, raw materials, and properties of biochar. Scanning electron microscope and colony forming unit analysis are commonly used to verify the immobilization efficiency. Applying biochar-immobilized bacteria can improve soil quality, plant growth, and crop yield.
