background: in this study, the pilot production of aerobic bioreactor tropical theileriosis vaccine was optimized with the aim of immunological assays for further mass production. methods: we have shown earlier the delayed type hypersensitivity (dth) assay could be used for evaluating the immunity and memory cells against specific theileria antigen in vaccinated animals. in addition, tnf-α is t...
Scleractinian corals (phylum Cnidaria, class Anthozoa) have innate immunological responses against infections. Research has recently suggested that corals also possess an adaptive-like immunological repertoire that recognizes specific pathogens and allografts. While evolutionarily distinct, the corals' innate and adaptive-like immunity systems are not mutually exclusive because the phagocytic c...
A variety of psychosocial factors have been shown to influence immunological responses in laboratory primates. The present investigation examined the effects of social housing condition on cell-mediated immune responses, comparing rhesus macaques (Macaca mulatta) in three housing conditions (single, pair, and group). Subjects included 12 adults of both sexes in each housing condition (N=36). Mu...
the increasing prevalence of chronic diseases, e.g., cardiovascular disease, diabetes and neuronal degenerative disease, present a challenge to find more effective therapies. stem cell-based therapy, including embryonic, umbilical cord blood and adult stem cells provides a rational treatment tool for regenerative medicine and has the potential to revolutionize modern therapy. however, there are...
BACKGROUND Oral administration of BCG was the route initially used by Calmette and Guérin, but was replaced by intradermal administration in virtually all countries after the Lubeck accident. However, Brazil continued to administer oral BCG Moreau RDJ, which was maintained until the mid-1970s when it was substituted by the intradermal route. Although BCG vaccination has been used in humans sinc...

some specific and non-specific immune variables of rainbow trout were assessed following vaccination of fish with formalin killed cells (fkc) and fkc containing extra cellular products (ecp) of s. iniae. rainbow trout weighing 80-100 g were vaccinated by intraperitoneal (i.p), dip and oral routes using fkc and fkc plus ecp with or without fround adjuvant (fa) at 16-17°c.antibody titration, lyso...
Generating tier 2 HIV-neutralizing antibody (nAb) responses by immunization remains a challenging problem, and the immunological barriers to induction of such responses with Env immunogens remain unclear. Here, some rhesus monkeys developed autologous tier 2 nAbs upon HIV Env trimer immunization (SOSIP.v5.2) whereas others did not. This was not because HIV Env trimers were immunologically silen...
