Dendritic cells are professional antigen presenting cells, which show an extraordinary capacity to initiate primary immune responses by stimulating T cells. This established function of dendritic cells has attracted much attention in efforts to develop useful vaccines for the treatment of cancer and infectious diseases. Designing effective strategies to generate clinical dendritic cell-based va...

Background: Falciparum malaria is a severe health burden worldwide. Antigen presenting cells are reported to be affected by erythrocytic stage of the parasite. Malarial hemozoin (HZ), a metabolite of malaria parasite, has adjuvant properties and may play a role in the induction of immune response against the parasite. Objective: To determine the immunological impact of hemozoin on the capacity ...

Acute myeloid leukemia (AML) is a type of poor prognosis hematological malignancies characterized by heterogeneous clonal expansion of myeloid progenitors. Leukemic stem cells are thought to form the majority of a cell population in minimal residual diseases (MRDs) which are resistant to current chemotherapeutic regimens and mediate disease relapse. Current therapeutic vaccine strategies have d...

INTRODUCTION Efferocytosis is a crucial process by which apoptotic cells are cleared by phagocytes, maintaining immune tolerance to self in the absence of inflammation. Peripheral tolerance, lost in autoimmune processes, may be restored by the administration of autologous dendritic cells loaded with islet apoptotic cells in experimental type 1 diabetes. OBJECTIVE To evaluate tolerogenic prope...

BACKGROUND Abnormal immune responses are believed to be highly relevant in the pathogenesis of chronic obstructive pulmonary disease (COPD). Dendritic cells provide a critical checkpoint for immunity by their capacity to both induce and suppress immunity. Although evident that cigarette smoke, the primary cause of COPD, significantly influences dendritic cell functions, little is known about th...

background: mesenchymal stem cells (mscs) possess a wide range of immunomodulatory functions mostly in immune cells including dendritic cells (dcs). dcs are the key cells in the immune response and play an important role in initiating cell-mediated immunity. objective: to evaluate the immunomodulatory effects of mscs supernatant on maturation and function of dcs. methods: bone marrow derived mi...
