Problem: Despite being at increased risk for severe COVID-19, pregnant women were initially excluded from vaccine clinical trials, which limited data regarding vaccine effectiveness and protection in this group. Aiming to better understand the immune response to vaccination during pregnancy, we compared the kinetics and titers of neutralizing and IgG antibodies generated against SARS-CoV-2 during vaccination with BNT162b2 (Pfizer-BioNTech) or CoronaVac (Sinovac Biotech) in a cohort of pregnant women.
Methods Of Study: We evaluated participants before vaccination and 30 days after each vaccine dose, using a multiplex bead assay to measure IgG antibodies against SARS-CoV-2 antigens (total spike, spike-1, spike-2, receptor binding domain, and nucleocapsid) and a live virus fluorescence reduction neutralization assay (FRNA) to quantify neutralizing antibodies.
Results: Our data showed that vaccination resulted in a robust humoral response, with a considerable increase in the levels of IgG and neutralizing antibodies after the first vaccine dose and a sustained neutralizing response after the vaccine boost. In addition, antispike IgG assays presented a slight decrease after the second dose, while the neutralization rate remained stable.
Conclusions: Immune response to the SARS-CoV-2 vaccine in pregnant women demonstrated an important increase in neutralizing antibodies.

Cardiac dysfunction is a serious complication of sepsis-induced multiorgan failure in intensive care units and is characterized by an uncontrolled immune response to overwhelming infection. Type 2 innate lymphoid cells (ILC2s), as a part of the innate immune system, play a crucial role in the inflammatory process of heterogeneous cardiac disorders. However, the role of ILC2 in regulating sepsis-induced cardiac dysfunction and its underlying mechanism remain unknown.

Introduction: Recent studies have underscored the importance of genetic factors in predicting COVID-19 susceptibility and severity. While cytokine storms are crucial in disease severity, genetic predisposition significantly influences immune responses. Our study examined genes related to SARS-CoV-2 invasion ) and interferon-induced immunity ().

Background: Osteosarcoma, an aggressive bone malignancy predominantly affecting children and adolescents, presents significant therapeutic challenges with a 5-year survival rate below 30% in metastatic cases. T-cell exhaustion, characterized by the overexpression of immune checkpoint molecules, contributes to osteosarcoma progression and immune evasion. Although targeting these inhibitory pathways has shown potential in restoring T-cell activity, the molecular regulators of T-cell depletion in osteosarcoma are poorly understood.
