What else can I help you with?
Where do antigens, the substances that trigger an immune response in the body, originate from?
Antigens, which trigger the immune response in the body, originate from foreign substances like bacteria, viruses, and other pathogens, as well as from the body's own cells that have been altered or damaged.
Where do antibodies originate in the body?
Antibodies originate in the body from specialized white blood cells called B cells. These B cells produce antibodies in response to foreign substances, such as viruses or bacteria, to help the immune system fight off infections.
How do dendritic cells activate T cells in the immune response?
Dendritic cells activate T cells in the immune response by presenting antigens to the T cells. This interaction triggers the T cells to become activated and initiate an immune response against the specific antigen.
What activates helper T cells in the immune response?
Helper T cells in the immune response are activated by antigens presented by antigen-presenting cells, such as dendritic cells. This activation process helps coordinate and regulate the immune response against pathogens.
How do B cells activate T cells in the immune response?
B cells activate T cells in the immune response by presenting antigens to T cells. This interaction triggers the T cells to become activated and multiply, leading to a coordinated immune response against the invading pathogen.

What are response cells?
Response cells are cells that respond to the immune system and react to diseases.
How do dendritic cells activate T cells in the immune response?
Dendritic cells activate T cells in the immune response by presenting antigens to the T cells. This interaction triggers the T cells to become activated and initiate an immune response against the specific antigen.

B cells activate T cells in the immune response by presenting antigens to T cells. This interaction triggers the T cells to become activated and multiply, leading to a coordinated immune response against the invading pathogen.
Do T cells secrete cytokines as part of their immune response?
Yes, T cells secrete cytokines as part of their immune response.
How do cytotoxic T cells contribute to the adaptive immune response?
Cytotoxic T cells play a crucial role in the adaptive immune response by identifying and destroying infected or abnormal cells in the body. They recognize specific antigens on these target cells and release toxic substances to kill them, helping to eliminate the threat and prevent further infection.
What cells help regulate antibody-mediated immune response?
Epidermal cells that aid in the immune response include melanocytes.
How are CD4 T cells activated in the immune response?
CD4 T cells are activated in the immune response when they recognize antigens presented by antigen-presenting cells, such as dendritic cells. This recognition triggers the CD4 T cells to proliferate and differentiate into effector T cells, which help coordinate and regulate the immune response.
What are the specific defenses in the immune system?
Specific defenses in the immune system include antibodies produced by B cells, which recognize and neutralize specific pathogens. T cells can also destroy infected cells and regulate the immune response. In addition, memory cells are formed after an infection, allowing for a quicker and stronger response upon reinfection.
Which are the myeloid cells?
Myeloid cells are a group of blood cells that originate from bone marrow and play crucial roles in the immune response. They include various types of cells such as monocytes, macrophages, neutrophils, eosinophils, basophils, and dendritic cells. These cells are involved in processes like phagocytosis, inflammation, and the adaptive immune response. Myeloid cells are essential for both innate and adaptive immunity, contributing to the body's defense against pathogens and tissue repair.
