Immature DCs are therefore considered to be part of the innate phase of pulpal immune response.Persistent infection leads to the activation of adaptive immunity. A transition to an adaptive immune response will take place in the dental pulp as the caries and bacteria approach the pulp. Antigens are recognized individually and lines of lymphocytes are developed to produce specific antibodies which attach to the recognized cells and initiate their destruction. Phagocytes remove the remains. B cells and T cells are the major lymphocytes involved.A variety of cytokines have been observed in the pulp. Patients with symptomatic and asymptomatic irreversible pulpitis have been shown to have an almost 23-fold increase in the cytokine IL-8 in the pulp. Cytokines in the pulp interact with each other. The ultimate effect on pulpal inflammation and healing is dependent upon the integrated actions of these inflammatory mediators.In addition to the lymphocytes, macrophages also provide defense against certain intracellular pathogens. Activated macrophages can function as class II antigen-presenting cells, similar to pulpal dendritic and B cells. In addition, activated macrophages secrete many inflammatory mediators.Macrophages in the pulp become activated after receiving two signals. The first is a priming stimulus and the second is an activating signal. The priming stimulus is secreted by activated T-helper cells. The activating stimulus may include bacterial lipopolysaccharides, muramyl dipeptide, and other chemical mediators.Macrophages are professional phagocytes in innate immune responses.
Alcoholic cardiomyopathy is a disease in which the chronic long-term abuse of alcohol (i.e., ethanol) leads to heart failure. Alcoholic cardiomyopathy is a type of dilated cardiomyopathy. Due to the direct toxic effects of alcohol on heart muscle, the heart is unable to pump blood efficiently, leading to heart failure. It can affect other parts of the body if the heart failure is severe. It is most common in males between the ages of 35 and 50. Signs and symptoms
Signs and symptoms presented by the occurrence of alcoholic cardiomyopathy are the result of the heart failing and usually occur after the disease has progressed to an advanced stage. Therefore, the symptoms have a lot in common with other forms of cardiomyopathy. These symptoms can include the following:
Ankle, feet, and leg swelling (edema)
Overall swelling
Loss of appetite
Shortness of breath (dyspnea), especially with activity
Breathing difficulty while lying down
Fatigue, weakness, faintness
Decreased alertness or concentration
Cough containing mucus, or pink, frothy material
Decreased urine output (oliguria)
Need to urinate at night (nocturia)
Heart palpitations (irregular heart beat)
Rapid pulse (tachycardia)

Diagnosis
Abnormal heart sounds, murmurs, ECG abnormalities, and enlarged heart on chest x-ray may lead to the diagnosis. Echocardiogram abnormalities and cardiac catheterization or angiogram to rule out coronary artery blockages, along with a history of alcohol abuse can confirm the diagnosis. Treatment
Treatment for alcoholic cardiomyopathy involves lifestyle changes, including complete abstinence from alcohol use, a low sodium diet,  and fluid restriction, as well as medications.
