IMMUNOTHERAPY

-

 Immunotherapy is a treatment that helps the body’s own immune system fight diseases such as cancer, autoimmune disorders, and infections. It works in two main ways: by boosting the immune system’s natural activity or by giving lab-made substances that help the immune system find and destroy abnormal cells. Examples include immune checkpoint inhibitors, which remove the “brakes” that stop immune cells from attacking cancer, and cellular therapies like CAR T-cell therapy, where a patient’s immune cells are modified to specifically target and kill cancer cells.

How Immunotherapy Works

  • Strengthening the Immune Response: It boosts the body’s natural immune cells, like T cells, so they can better recognize and attack cancer cells that might otherwise escape detection.

  • Blocking Immune Evasion: Some cancer cells use special signals to “hide” from the immune system. Immunotherapy blocks these signals, allowing immune cells to find and destroy the cancer.

  • Providing Immune Components: Lab-made antibodies or proteins (such as cytokines) can be given to support and guide the immune system.

  • Cellular Therapy: In treatments like CAR T-cell therapy, a patient’s immune cells are taken out, modified in the lab to recognize cancer, and then returned to the body to mount a stronger attack.

Examples of Conditions Treated with Immunotherapy

  • Cancer: Widely used to help the immune system target and eliminate cancer cells.

  • Autoimmune Diseases: Can regulate the immune system to stop it from attacking the body’s own tissues, such as in rheumatoid arthritis or multiple sclerosis.

  • Immunodeficiencies & Infectious Diseases: Can help strengthen or balance immune responses in conditions like immune deficiencies and chronic infections.

Potential Benefits

  • Targeted Action: Unlike chemotherapy, which affects both healthy and diseased cells, immunotherapy works with the body’s own defense system, often causing fewer side effects.

  • Extended Survival: For many cancer patients, immunotherapy has been shown to improve survival and quality of life.

Staphylokinase (Sak) and Streptokinase (SK)

-
Staphylokinase (Sak)  and  Streptokinase (SK)  are fascinating enzymes with a dual identity—used both in medicine and by bacteria as virulence factors. Medically, streptokinase (produced by  Streptococcus pyogenes ) has long been used as a clot-dissolving drug in conditions like heart attacks, deep vein thrombosis, and pulmonary embolism. It is cost-effective but has notable drawbacks, including a high risk of systemic bleeding due to its non-specific action and the potential to trigger immune reactions, especially upon repeated use. In contrast, staphylokinase (from  Staphylococcus aureus ) is still under clinical investigation but shows promise as a more clot-specific alternative, acting mainly at the site of clots and posing a lower bleeding risk. However, its clinical application is limited so far due to slower activation and ongoing trials. From a pathogenic standpoint, both enzymes help bac...

Activation of Yellow marrow into Red marrow

-
 When the body senses a shortage of blood cells , it sends signals to reactivate the yellow bone marrow. 1. Detection of Blood Cell Shortage In conditions like anemia , injury , or infection , there are not enough red blood cells (RBCs) or other blood cells. The body detects low oxygen levels or low cell counts in the blood.  2. Signal Release The kidneys release a hormone called erythropoietin (EPO) . Cytokines (immune signaling proteins) are also released. These signals reach the bone marrow through the blood.  3. Stem Cell Activation in Yellow Marrow The yellow marrow contains mesenchymal stem cells (fat-storing stem cells). Under normal conditions, these produce fat. But in response to signals (like EPO and cytokines), they start converting into hematopoietic cells (blood-producing cells). 4. Fat Cells Decrease Fat cells in yellow marrow shrink or die off . More space opens up for blood-forming cells to grow. 5. Re...

Complement system

-
  Complement system is significant part of innate immune system.it contains 30 proteins in blood plasma and on the surface of the cell which will activate as a chain reaction (one will activate the next) Following are the major functions of complement system. Opsonization- label the microbes so that the phagocytic cells will get activated Chemotaxis-Attract the immune cells to the infected site Cell lysis- Forms a membrane attack complex (MAC) that can directly kill bacteria Clearance of Immune complexes- Helps to remove  antibody antigen complex from the body Pathways 1. Classical pathway classical pathway will be triggered by the antibodies and it comes under the part of adaptive immunity. Example If a person got infected with the measles virus . The body will start produced IgG antibodies against the virus. These antibodies bind to the virus. The classical pathway is activated to destroy the virus . classical pathway needs antibodies to induce the immune response . 2. Lect...
