Summary: Characterization of T cell responses in convalescent individuals from SARS-CoV-2 infection revealed unique phenotypes and a coordinated immune response, with specific CD8(+) T cell responses directed against various epitopes from the virus proteome. The differentiation of T cells into stem cell and transitional memory subsets may be crucial for developing lasting protection against the virus.

Summary: Despite the recent emergence of COVID-19, research studies have already developed and utilized multiple animal models to unravel the mysteries of the disease and gain insights into the biology of SARS-CoV-2. However, there are significant challenges in studying this virus in model organisms, such as poor infectivity of clinical isolates in certain species and the lack of key features seen in COVID-19 patients. Moreover, the age-related susceptibility of severe COVID-19 poses difficulties when using young and immunologically naive laboratory animals for testing. This review discusses the animal models developed so far, highlighting the unique advantages of the zebrafish model in understanding and addressing the disease.

Summary: The study found that COVID-19 in Brazil is spreading rapidly across municipalities with distinct spatial and temporal patterns of clustering, trajectories, and speed. Analysis shows that inadequate policy measures have led to high transmission and mortality burdens. The current surge in cases and deaths, along with the circulation of concerning variants, highlights the need for government to strengthen prevention and control measures.

Summary: COVID-19 pathophysiology is largely influenced by immune deregulation, resulting in various severe consequences such as immune system malfunction, endothelial activation and inflammation, as well as immunothrombosis. These insights could potentially offer new opportunities in disease prevention and treatment.

Summary: LY-CoV555, a neutralizing antibody, showed promising results in reducing viral load, improving symptoms, and lowering the risk of hospitalization among patients with mild or moderate Covid-19. While one of the doses appeared to accelerate the decline in viral load, others did not show significant effects by day 11.

Summary: The SARS-CoV-2 virus in the B.1.351 variant discovered in South Africa can evade neutralization by most antibodies when expressed, but does not affect binding by convalescent plasma. This suggests the potential for reinfection with antigenically distinct variants and predicts reduced efficacy of spike-based vaccines.

Summary: This study aimed to understand adaptive immunity to SARS-CoV-2 by analyzing B cell epitopes and neutralizing activity in COVID-19 patients. Most patients showed neutralizing activity against SARS-CoV-2, with antibodies targeting the S protein or RBD, and a correlation between neutralizing antibody titer and IgG antibody titer. Analysis of patient serum revealed potential targets for vaccine development against SARS-CoV-2.

Summary: This study found strong correlation between the functionality of COVID-19 convalescent plasma and polyclonal antibody targeting of specific peptides in the SARS-CoV-2 spike protein. Antibody responses to specific coronaviruses correlated with the development of highly neutralizing antibodies against CoV-2. Plasma donations reactive to the CoV-2 spike receptor binding domain had higher neutralizing titers.

Three aberrantly expressed ncRNAs were identified as potential biomarkers for differentiating MGT subtypes. YRNA and tRFs expression levels were found to be decreased in metastatic compared to primary MGT cell lines.

Summary: In this study, the researchers used signal analysis to study the instantaneous amplitude and phase of sarcomeric oscillations in skeletal muscle. They identified two types of oscillations, sarcomeric oscillations and sarcosynced oscillations, and visualized their behavior during propagating waves. The researchers discovered the presence of sarcomeric defect holes and sarcomeric collision holes, which are important indicators for understanding the oscillation properties of sarcomeres. This finding has important implications for improving our understanding of muscle function and its regulatory mechanisms.

Summary: This study found that low expression of TP53INP2 is associated with poor survival in colorectal cancer (CRC) patients. As the malignancy of CRC progresses, TP53INP2 expression gradually decreases. Knockdown of TP53INP2 promotes CRC cell proliferation and tumor growth. Mechanistically, TP53INP2 deficiency decreases phosphorylation of beta-catenin, leading to increased accumulation and enhanced nuclear translocation and transcriptional activity. Additionally, TP53INP2 sequesters TIM50, inhibiting its activation of beta-catenin. In conclusion, downregulation of TP53INP2 promotes CRC progression by activating beta-catenin.

Summary: Oligomeric enzymes are known for their higher catalytic rates compared to monomeric enzymes, but the extent of additivity in their activity is still not well understood. This study used tetrameric rabbit lactate dehydrogenase as a model to examine the kinetics of its catalytic action. Surprisingly, when the concentration of the limiting reactant exceeded that of a single subunit, there was a significant slowdown in the enzyme's conformational rearrangements.

Summary: The fatty acid elongation enzyme ELOVL5 plays a critical role in promoting metastasis in prostate cancer. Knocking down ELOVL5 leads to the accumulation of malonyl-CoA, which inhibits fatty acid oxidation in mitochondria. This study highlights the importance of fatty acid elongation in regulating cell viability and provides a potential target for prostate cancer treatment.
