Summary
Understanding Leishmania infection requires studying immune responses. This review details key immunological factors in resistance, susceptibility, and disease progression for leishmaniasis, emphasizing human cases.
Area of Science:
- Immunology
- Parasitology
- Infectious Diseases
Background:
- Leishmania parasites are studied to understand immune responses in infection.
- Host immune status and parasite species influence Leishmania infection outcomes.
- Most exposed individuals do not develop overt disease, highlighting protective immunity.
Purpose of the Study:
- To provide an updated overview of immunological responses in leishmaniasis.
- To emphasize the roles of various immune cells and T-cell subsets in disease.
- To focus on immunological aspects relevant to human leishmaniasis.
Main Methods:
- Review of recent studies on immune responses to Leishmania major.
- Analysis of immunological events in skin infection models.
- Synthesis of current knowledge on T-helper (Th) 1, Th2, regulatory T-cells, and Th17 cells.
Main Results:
- The Th1/Th2 paradigm is an oversimplification of immune responses to Leishmania.
- Th2 polarization does not fully explain the severity of human leishmaniasis.
- Regulatory T-cells and Th17 cells play significant roles in susceptibility and resistance.
Conclusions:
- A comprehensive understanding of immune responses is crucial for developing vaccines and therapies for leishmaniasis.
- Beyond Th1/Th2, other T-cell subsets are critical for controlling Leishmania infection.
- Further research into these complex immune interactions is needed for effective leishmaniasis management.

01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:21Antiprotozoal Agents
Leishmaniasis is a widespread parasitic disease caused by several Leishmania species. It affects millions of people each year and remains a major public health problem in endemic regions. First-line treatment relies on pentavalent antimonials, including meglumine antimoniate and sodium stibogluconate. Even so, how these drugs work has not been fully clear, especially their interaction with parasite-specific biochemical pathways. One key target is trypanothione reductase (TR), an enzyme that...
01:29Malaria
Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
01:27Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

01:25Immunodeficiency Diseases
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

01:22Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
