The present report meta-analyzes more than 300 empirical articles describing a relationship between psychological stress and parameters of the immune system in human participants. Acute stressors (lasting minutes) were associated with potentially adaptive upregulation of some parameters of natural immunity and downregulation of some functions of specific immunity. Brief naturalistic stressors (...

Human cases of infection due to a novel swine-origin variant of influenza A virus subtype H3N2 (H3N2v) have recently been identified in the United States. Pre-existing humoral and cellular immunity has been recognized as one of the key factors in limiting the infection burden of an emerging influenza virus strain, contributing to restrict its circulation and to mitigate clinical presentation. A...

The objective of this study was to compare immune responses induced in BALB/c mice following immunization with pcDNA-GPV-VP2 DNA by gene gun bombardment (6 μg) or by intramuscular (im) injection (100 μg) with the responses to live attenuated vaccine by im injection (100 μl). pcDNA3.1 (+) and physiological saline were used as controls. Peripheral blood samples were collected at 3, 7, 14, 21, 28,...

BACKGROUND AND OBJECTIVE Cellular immunity abnormalities are associated with sarcoidosis. Normal cellular immunity is required for adequate humoral immunity; therefore, a decreased humoral immune response is possible in patients with sarcoidosis. We evaluated humoral immunity by vaccinating patients with sarcoidosis against tetanus. PATIENTS AND METHOD We screened 60 patients with sarcoidosis...

The objective of modern vaccine development is the safe generation of protective long-term immune memory, both prophylactic and therapeutic. Live attenuated vaccines generate potent cellular and humoral immunity [1-3], but numerous problems exist with these vaccines, ranging from production and storage issues to adverse reactions and reversion to virulence. Subunit vaccines are safer, more stab...

A currently popular hypothesis states that the expression of carotenoid-dependent sexual ornaments and immune function may be correlated because both traits are positively affected by carotenoids. However, such a correlation may arise for another reason: it is well known that immune function is dependent on nutritional condition. A recent study has suggested that the expression of ornaments may...

we have previously shown the adjuvant activity of propranolol (prp) (a beta-adrenergic receptor antagonist) using a vaccine model for salmonella typhimurium. in this study prp was used as an adjuvant in combination with plasmodium  berghei  (p. berghei)  whole blood stage (pwbs) antigens. balb/c mice were immunized three times with a 2-week interval, either pwbs vaccine alone or in combination ...
