Comparative monocyte and T cell responses in DENV-exposed subjects from South-East Asia and DENV-naïve residents in Taiwan.

Background/purpose(s): Dengue virus (DENV) is one of the most troublesome mosquito-borne infectious viruses in tropical and subtropical zones. People with secondary/multiple DENV infections are at an increased risk of developing severe dengue. Both monocytes and T cells are known to play important roles in the immune response against DENV.

Mobilization of Hematopoietic Stem and Progenitor Cells during Dengue Virus Infection.

Hematopoietic stem and progenitor cells (HSPCs) mobilization is the movement of HSPCs from the bone marrow to the peripheral blood or tissue induced by stress. HSPC mobilization is a well-known response to protect the host during infection through urgent differentiation of HSPCs to immune cells. Dengue virus (DENV) infection is known to cause stress in infected humans and the mobilizing capacity of HSPCs during DENV infection in affected patients has not been fully investigated.

Identification and characterization of permissive cells to dengue virus infection in human hematopoietic stem and progenitor cells.

Background: Dengue virus (DENV) is a significant threat to public health in tropical and subtropical regions, where the frequency of human migration is increasing. Transmission of DENV from donors to recipients after hematopoietic stem cell transplantation has been steadily described. However, the underlying mechanisms remain unclear.

Transient Monocytosis Subjugates Low Platelet Count in Adult Dengue Patients.

Background: Dengue is one of the most important vector-borne human viral diseases globally. The kinetic changes of hematological parameters of dengue in adult Taiwanese patients have seldomly been systematically investigated and characterized.

Methodology/principal Findings: Serial laboratory data of 1,015 adult patients who were diagnosed with dengue virus serotype 2 (DENV2) and 3 (DENV3) infections in southern Taiwan were retrospectively examined.
