Tumor Immunotherapy

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Development of Immunocompetence

Development 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...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...

Summary

This summary is machine-generated.

This study investigated the immune-boosting effects of Sorbus sibirica, Calendula officinalis, and Althaea officinalis extracts. These plant extracts show comparable or superior immune stimulation compared to Echinacea purpurea tincture.

Area of Science:

Immunology
Pharmacognosy
Natural Products

Background:

Cyclophosphamide is a common immunosuppressive drug.
Natural compounds are explored for immunomodulatory effects.
Assessing plant extracts' impact on immune function is crucial.

Purpose of the Study:

To evaluate the immunomodulatory potential of Sorbus sibirica, Calendula officinalis, and Althaea officinalis extracts.
To compare their efficacy against Echinacea purpurea tincture in mice.
To investigate their effects on humoral immunity and nonspecific resistance.

Main Methods:

Mice were treated with plant extracts and cyclophosphamide.
Humoral immune response was assessed.
Nonspecific resistance was evaluated through macrophage activity (peritoneal and peripheral blood).

Main Results:

Sorbus sibirica, Calendula officinalis, and Althaea officinalis extracts stimulated humoral immune response.
These extracts matched Echinacea purpurea tincture in enhancing peritoneal macrophage phagocytic and bactericidal activity.
The studied extracts demonstrated superior enhancement of peripheral blood neutrophil phagocytic activity compared to Echinacea purpurea.

Conclusions:

Sorbus sibirica, Calendula officinalis, and Althaea officinalis possess significant immunomodulatory properties.
These extracts offer a potential natural alternative or adjunct for immune support.
Further research into their mechanisms of action is warranted.
