The pro-inflammatory responses of innate immune cells to Leishmania RNA virus 2-infected L. major support the survival and proliferation of the parasites.

Infection of Leishmania by Leishmania RNA virus (LRV) has been proposed as a pathogenic factor that induces pro-inflammatory responses through the TLR3/TLR4 signaling pathway. We investigated the effect of L. major infection by LRV2 on innate immune cell responses (human neutrophil (HL-60) and macrophage (THP-1) cell lines).

PLGA nanoparticle-delivered Leishmania antigen and TLR agonists as a therapeutic vaccine against cutaneous leishmaniasis in BALB/c mice.

Leishmaniasis, caused by Leishmania (L.) species, remains a neglected infection. Therapeutic vaccination presents a promising strategy for its treatment.

Differential Expression of miR-146 and miR-155 in Active and Latent Tuberculosis Infection.

Background: Tuberculosis (TB) is one of the leading causes of death worldwide. Besides, one-third of the world population is infected with (MTB) while staying clinically asymptomatic; the situation is called latent TB infection (LTBI). MiR-21, miR-31, miR-146a, and miR-155 play an important role in many immune and inflammatory pathways.

The role of microbiota and immune system crosstalk in cancer development and therapy.

Cancer is a multifactorial disease that is the second leading cause of death after cardiovascular disease in the world. In recent years, microbiota's role in the regulation and homeostasis of the immune system has been considered. Moreover, the immune system can affect the microbiota content.

Impact of gut microbiota on immune system.

The commensal microflora collection known as microbiota has an essential role in maintaining the host's physiological homeostasis. The microbiota has a vital role in induction and regulation of local and systemic immune responses. On the other hand, the immune system involves maintaining microbiota compositions.

Combinatorial delivery of antigen and TLR agonists via PLGA nanoparticles modulates Leishmania major-infected-macrophages activation.

Appropriate activation of macrophages is critical for the elimination of Leishmania parasites, which resides in this cell. Some species of Leishmania (L.) fails to stimulate macrophages and establish a chronic infection.
