Different sources of antibodies can provoke different kinds of immune responses. For example, the human immune system can recognize mouse antibodies (also known as murine antibodies) and trigger an immune response against them. This could reduce the effectiveness of the antibodies as a treatment and cause an immune reaction.
Immunosuppressive drugs have the potential to cause immunodeficiency, which can increase susceptibility to opportunistic infection and decrease cancer immunosurveillance. [9] Immunosuppressants may be prescribed when a normal immune response is undesirable, such as in autoimmune diseases. [10]
They can be endogenous (produced naturally within the body) or exogenous (as pharmaceutical drugs), and they can either enhance an immune response or suppress it. Some of these substances arouse the body's response to an infection , and others can keep the response from becoming excessive.
Some drugs can cause a neutralizing immune response, meaning that the immune system produces neutralizing antibodies that counteract the action of the drugs, particularly if the drugs are administered repeatedly, or in larger doses.
There could be new hope on for kidney cancer patients. Researchers announced early results of an anti-tumor vaccine for patients with stage 3 or 4 kidney cancer, who face high recurrence risk.
Cancer cell heterogeneity can cause disease progression when molecularly targeted therapy, fails to kill those tumor cells which do not express the marker, then divide and mutate further, creating a new heterogeneous tumour. In breast cancer models of the mouse the immune microenvironment affects susceptibility to neoadjuvant chemotherapy. In ...
Immunosuppressive drugs can be used to control the immune system with organ transplantation and with autoimmune disease. Immune responses depend on lymphocyte proliferation. Lymphocyte proliferation is the multiplication of lymphocyte cells used to fight and remember foreign invaders. [60]
All cancer treatment modalities (e.g., chemotherapy, targeted drugs, radiation and surgery) trigger systemic and local effects in the treated subject (i.e., the host). These include a rapid elevation in the levels of circulating cytokines , chemokines , growth factors and enzymes accompanied by acute mobilization and tumor homing of bone-marrow ...
