Plantar warts commonly found on the bottom of the foot are caused by a virus and can cause irritation. Athlete's foot, which is caused by a fungus, also can lead to foot irritation. A common cause of foot pain is the ingrown toenail.
The adaptive defense consists of antibodies and lymphocytes, often called the humoral response and the cell mediated response. The term âadaptiveâ refers to the differentiation of self from non-self, and the tailoring of the response to the particular foreign invader.he adaptive defense consists of antibodies and lymphocytes, often called the humoral response and the cell mediated response.

Innate immune defenses. In response to viral infection, many organisms mount a remarkable defense known as the immune response. This response to viral infection consists of an innate, or nonspecific component, and an adaptive, or specific defense.The innate response is considered the first line of immune defense because it is active even before infection begins.ays to weeks are required to mount an adaptive immune response that is specifically tailored to the infecting virus. The innate response therefore serves as a crucial rapid response that provides sufficient time for the activation of the adaptive immune system.
