Summary: Cas13a delivered to the lung of mice and hamsters inhibits replication of influenza virus and SARS-CoV-2, suggesting that Cas13a-mediated targeting of pathogenic viruses can mitigate respiratory infections. The study successfully reduced viral RNA levels in the lung tissue of animals, demonstrating the efficacy of Cas13a in targeting RNA viruses.

Summary: The World Health Organization's goal of eliminating Hepatitis C virus (HCV) by 2030 using direct-acting antiviral treatments has become less attainable post the 2020 pandemic of coronavirus disease 2019. Therefore, a more realistic approach of micro-elimination in population segments where targeted strategies of prevention and treatment are easily attained has been promoted in Europe. Active involvement of stakeholders and community participation are essential components for the success of a micro-elimination project tailored at the geographical level according to HCV epidemiology and individual country's income.

Summary: Hemodialysis patients are at increased risk of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. This study found that hemodialysis patients with HCV exhibited a higher burden of comorbidities, especially in ischemic heart diseases, respiratory disorders, and mental/behavioral disorders, compared to patients with HBV and those without viral hepatitis.

Summary: Hepatitis is a significant cause of mortality worldwide, with around 1.34 million deaths annually. Africa is not immune to this issue, with an estimated 100 million individuals infected with Hepatitis B or C. The continent, already fragile, is further burdened by the onset of the COVID-19 pandemic, which could potentially worsen the threat from viral diseases like Hepatitis. Strengthening prevention policies is essential for Africa to build resilience against such threats.

Summary: This study identified immunodominant CD8+ CTL epitopes for PRRSV-2 M protein and predicted their binding to SLA I molecules through a combination of ELISPOT assays and SLA genotyping. In vitro assays confirmed the formation of immune complexes between specific peptides and SLA class I molecules. These potential CTL epitopes represent a promising avenue for further research into T cell-based vaccine development for PRRSV.

Summary: The COVID-19 pandemic has led to a race towards the development of therapies and preventive strategies, with antibodies and vaccines being particularly attractive due to their specificity, low drug-drug interaction risk, and potential long-lasting protective effects. However, the implementation of these strategies should consider safety concerns, as potential adverse events like ADE and CSS have been reported. Depletion of T-cells in COVID-19 patients is associated with poor prognosis, suggesting a role for vaccines inducing cellular immunity to mitigate the risks of ADE and CSS.

Summary: Hepatitis B virus infection is a global health issue with no eradicative therapy available. The lack of validated T cell epitopes hampers the development of vaccines and T cell therapies, with most epitopes restricted to common HLA supertypes. More research is needed to map a comprehensive repertoire of T cell epitopes covering the HBV proteome and global populations.

Summary: This study systematically summarized the prevalence of HIV, HBV, and HCV infections among incarcerated people in Iran. The results showed that the prevalences of these infections are relatively high in this population. Meta-analysis and regression analysis found a decrease in HIV and HCV infections over time.

Summary: The design of a clinical trial for a controlled human infection model (CHIM) to accelerate hepatitis C virus (HCV) vaccine development requires careful consideration. The design of a potential approach to HCV CHIM is outlined, involving initial sentinel cohorts to establish the safety and curability of the viral inoculum followed by larger cohorts to establish the spontaneous clearance rate for each inoculum. Additional considerations are discussed, including the populations to be enrolled, the required monitoring approach, indications for antiviral therapy, and the required sample size for different CHIM approaches. Finally, safety considerations for CHIM participants are discussed.

Summary: Hepatitis C virus (HCV) particles are stable when secreted from cells, but become highly unstable after freeze-thawing of producer cells. Cell-secreted proteins can protect HCV particles from degradation, specifically those that are lipidated and low-density. HCV particles are sensitive to oxidation, but can be protected from lipid oxidation by secreted factors.

Summary: Deep sequencing of hepatitis C virus (HCV) among self-described injecting partnerships showed that the majority of transmission events originate from outside of the injecting partnership, and the direction of transmission is often difficult to accurately infer, especially in high-risk networks with rapid transmission events.

Summary: The combination of 2‘3’-c ' diAM(PS)2 and Poly I:C as adjuvants can enhance DCs' ability to induce polyfunctional HIV-1 specific CD8(+) T-cell responses, reducing the severity of CD4(+) T-cell depletion following HIV-1 infection, and preserving the specific polyfunctional responses of CD8(+) T cells. The priming of DCs with PolyI:C and STING agonists may be useful for future HIV-1 vaccine studies.

Summary: Virus infections can enhance drug hypersensitivity reactions by inducing immune stimulation and increasing the interaction with immune receptors. In some cases, severe drug hypersensitivity reactions may precede the reactivation of herpes viruses. This phenomenon can be explained by the immune stimulation during drug reactions, which activates herpes-specific T cells and leads to the release of herpes viruses. These concepts explain the transient nature of drug hypersensitivity reactions during viral infections and the asymptomatic herpes-virus viremia after severe drug hypersensitivity reactions.

Summary: The HTI vaccines were able to induce strong, polyfunctional, and broad T-cell responses, but they did not prevent viral rebound. However, in some participants, these vaccines were associated with a longer time off antiretroviral treatment, suggesting that their immunogenicity may be beneficial for future cure approaches.

Summary: Mass vaccination campaigns have been effective in reducing COVID-19 transmission and severity. However, the immune responses developed in patients with predominantly antibody-deficiencies (PAD) after vaccination vary. Different PAD patients show different levels of response to the vaccine, highlighting the need for immunomonitoring and personalized therapeutic strategies.

Summary: High levels of SIRT2 are associated with uncontrolled HIV infection, plasma viral load, and proviral levels. SIRT2 levels are also linked to markers of neurological damage and brain involution, especially in individuals who initiate cART later. Inhibition of SIRT2 could potentially be a therapeutic target for HIV infections and their associated neurological dysfunction.

Summary: This study investigates the relationship between HLA-E expression and NK cell characteristics and functions. The findings suggest that increased HLA-E expression and changes in NK subpopulations are associated with chronic HIV infection. Uncontrolled HIV infection leads to dysfunction of NK cells, loss of HLA-E regulation, and reduced viral control. The study also demonstrates the potential sensitivity of target cells presenting HIV-derived epitopes to NK lysis. However, prolonged exposure to elevated HLA-E expression levels may result in NK cell dysfunction and reduced viral control in chronic infection.

Summary: The gut microbiota plays a crucial role in vaccine responses, and this study found that T-cell vaccination can alter the gut microbiota and promote the growth of bacteria that produce anti-inflammatory molecules. These changes in the microbiota are associated with immune responses and pro-inflammatory cytokines.

Summary: Eosinophilia is a common manifestation in drug hypersensitivity reactions, and its cause is unclear. However, it seems to be related to off-target activities of drugs with immune receptors, resulting in T-cell stimulation and excessive IL-5 production. This IL-5-TCR signalosome hypothesis may explain eosinophilia in various circumstances and provide new therapeutic options for eosinophilic diseases.

Summary: The study investigated the relationship between the reactivity pattern of drug-reacting T cells in drug allergic patients and their clinical manifestations. The results showed a shift from hapten pattern in mild allergic reactions to p-i pattern in severe life-threatening allergic reactions, indicating a need for reevaluation of preclinical risk assessment methods for new drugs.
