Dengue disease is more common with blood group O.
The observed variation in T cell response according to ethnicity could be related to the immunopathogenesis of dengue hemorrhagic fever, and may partially explain the epidemiological evidence that black individuals are at lower risk for the most severe dengue clinical course compared with white individuals.
This mechanism plays an important pathogenetic role in the development of complications associated with dengue virus infection, including dengue hemorrhagic infection and dengue shock syndrome.
To our knowledge, this is the first report demonstrating an association between ABO blood group and the severity of dengue disease.
This paper summarizes reports on the permissive cells in vitro and in vivo and suggests a hematological cell lineage for dengue virus infection in vivo, with the hope that a new focus will shed light on further understanding of the complexities of dengue disease.

How dengue affect platelet count?5 answersDengue virus infection affects platelet count by causing thrombocytopenia, which is a decrease in platelet levels. Thrombocytopenia is observed in both mild and severe cases of dengue, with the lowest platelet counts seen in severe cases. The decrease in platelet counts can be attributed to various mechanisms, including bone marrow suppression, consumption of platelets at the periphery, and platelet clearance mediated by anti-platelet antibodies. Additionally, the formation of viral antibody complexes stimulates platelet aggregation, leading to a decrease in platelet count. Dengue infection also affects platelet function, with alterations in platelet number and function contributing to thrombocytopenia. Platelets play a role in the immune and inflammatory response during dengue infection, and their activation and secretion of viral and host factors contribute to the pathogenesis of the disease. Overall, dengue infection has a significant impact on platelet count and function, highlighting the importance of monitoring platelet levels in dengue patients.
What is the relationship between white blood cells and parasitic infections?4 answersWhite blood cells play a role in parasitic infections. In the case of visceral leishmaniasis (VL), microRNAs (miRNAs) in peripheral blood mononuclear cells (PBMC) of infected dogs were found to be differentially expressed, suggesting that Leishmania infection interferes with miRNA expression in PBMC. Parasitic infections have also been linked to autoimmune diseases and allergic asthma through the "hygiene hypothesis." Regulatory T (Treg) cells and Th17 cells are believed to be involved in the interplay between parasitic infections and the hygiene hypothesis. Eosinophilia, characterized by an increase in eosinophils, is a common feature of trichinellosis in humans. Eosinophils are activated in response to T-helper 2 activation and are involved in the inflammatory response against Trichinella parasites. However, basophilia, an increase in basophil count, is rare in human parasitic infections and is not a useful clinical marker for evaluating suspected parasitic disease.

5 answers
Research has been conducted on finding similar transcriptomes in the Connectivity Map (CMap) database to screen drugs based on gene expression profiles. Various studies have explored methods to predict drug transcriptional response similarity from compound structures using signed graph convolutional networks (SGCN). Additionally, investigations have focused on matching drug effects with disease effects by analyzing gene regulatory networks and utilizing similarity scores and heuristics to identify potential drug candidates for repurposing. Furthermore, bioinformatics approaches have been employed to identify drugs with therapeutic effects against dengue virus based on transcriptomic data and gene expression profiles from patients. These studies highlight the significance of leveraging transcriptome data in the CMap database for drug discovery and repurposing efforts.
What is the incidence and prevalence of of malaria in 2023 as compared to 2022 in Pakistan?
4 answers
In Pakistan, the incidence and prevalence of malaria in 2023 are crucial concerns due to the significant impact of the disease. In 2022, Rahim Yar Khan district forecasted a range of malaria cases, with a minimum of 586.75 cases in June and a maximum of 1281.93 cases in October, emphasizing the ongoing threat. Additionally, the tribal districts of KPK province faced challenges in monitoring and controlling malaria, with a high prevalence of P. vivax cases, affecting young males predominantly. Furthermore, a study in Mardan reported a prevalence of 39.3% pre-COVID-19 and 41.9% post-COVID-19, indicating an increase in malaria cases due to limited healthcare access. These findings suggest that the incidence and prevalence of malaria in 2023 may continue to pose a significant public health burden in Pakistan.
Smad role in infection?
5 answers
Smad proteins play crucial roles in infections caused by various pathogens. In the context of Rift Valley fever virus (RVFV) infection, Smad transcription factors are highly phosphorylated, indicating their involvement in signaling cascades triggered by the virus. Similarly, in Zika virus (ZIKV) infection, TGF-β1 enhances viral binding and infection in trophoblasts through the Smad pathway. Moreover, during bacterial infections, hepcidin regulation via the BMP-Smad pathway influences iron availability for pathogens, impacting the course of infection. In liver fibrosis induced by Schistosoma japonicum, Smad2/3 and Smad7 are highly expressed, suggesting their involvement in the fibrotic process. Additionally, in the context of preterm birth, SMAD7 is implicated in regulating the inflammatory response induced by infections, highlighting its role in labor-associated inflammation.

What viruses have been cultured in pulmonary air-liquid interface cultures?
4 answers
Respiratory viruses such as Human coronavirus NL63 (HCoV-NL63), SARS-CoV-2 causing Covid-19, and Epstein-Barr virus (EBV)have been cultured in pulmonary air-liquid interface (ALI) cultures. These ALI models, derived from immortalized and primary cells, are utilized to study various respiratory infections, including HCoV-NL63 and SARS-CoV-2, which utilize the ACE2 receptor for cell entry. Additionally, ALI cultures have been instrumental in investigating EBV infection in the nasopharyngeal epithelium, demonstrating susceptibility to EBV in pseudostratified epithelium cells. The use of ALI cultures provides a valuable tool for studying viral infections in the respiratory tract, aiding in understanding pathophysiology, disease mechanisms, and potential therapeutic interventions.
