human cytomegalovirus is one of the most common pathogenic viruses all over the world. in congenital infection leads to neurologic severe disorders and even death of fetus and in individuals with immunosuppression may also cause severe clinical symptoms. multiple evidence indicate that among several strategies, epitope-based vaccine (evs) that can induce both humoral and cellular immunity respo...

BACKGROUND The etiologic agent of Chagas Disease is Trypanosoma cruzi. Acute infection results in patent parasitemia and polyclonal lymphocyte activation. Polyclonal B cell activation associated with hypergammaglobulinemia and delayed specific humoral immunity has been reported during T. cruzi infection in experimental mouse models. Based on preliminary data from our laboratory we hypothesized ...

In their opinion piece [1], Wilson and Karp discuss the poor durability of the anti-gp120 humoral response, an important feature that poses a significant difficulty for HIV vaccine development [2]. The authors make the case that short-lived anti-gp120 responses are not seen in all studies of HIV-envelope-based vaccines, suggesting that the problem might be solved via vaccine formulation strateg...

The association of multiple non-caseating granulomata and a positive Kviem test is normally considered to be indicative of a diagnosis of sarcoidosis. However, although depressed cell-mediated immunity is commonly described, it is extremely rare to find a humoral immune paresis. A patient is reported who had multiple granulomata, depressed cellular and humoral immunity and a positive Kveim test.

Immunity to reinfection in the genital tract of female guinea pigs with the agent of guinea pig inclusion conjunctivitis was found to be dependent upon an intact humoral immune response. Cell-mediated immunity in the absence of humoral immunity had no apparent role in resistance to challenge infection.

Our previous studies revealed that lactoferrin (LF) reconstitutes the cellular and humoral immune response in cyclophosphamide-treated mice. The aim of this investigation was to establish whether the suppressory effects of methotrexate (MTX) on the cellular and humoral immune response can be modulated by LF. We found that MTX, given intraperitoneally (i.p.) at a dose of 200 mg/kg b.w., 48 h fol...
