Lymphokines are secreted primarily by T-helper cells, particularly CD4+ T cells, which play a crucial role in regulating the immune response. These cytokines help activate other immune cells, including B cells and cytotoxic T cells, enhancing their ability to respond to pathogens. Additionally, macrophages and other immune cells can also produce lymphokines to support and modulate immune functions.
What else can I help you with?
Is adaptive immunity provided only by lymphocytes that secrete antibodies?
false
What is the function of what they secrete?
The substances that organisms secrete serve various essential functions, including facilitating communication, promoting growth, and aiding in defense. For instance, plants may secrete hormones to regulate growth and respond to environmental stimuli, while animals might secrete pheromones for communication and reproduction. Additionally, secretions such as mucus or venom can protect against predators or pathogens. Overall, these secretions play crucial roles in maintaining the organism's health and survival.

What are the functions of the epithalamus?
The main functions of the epithalamus is to secrete melatonin and regulate emotions. It also regulates the motor pathways of the human body.
What does humoral immunity involves?
The cells which are involved in the production of antibodies are known as B cells. These are effector cells which will secrete anybodies and activate the antigens.
