SARS-CoV-2 is a betacoronavirus, which induced severe pandemic infectious disease around the world. Even if several drugs have been suggested for its treatment, to date, only strategy reduce severity of represented by use vaccine. However, lack pre-marketing evidence in frail patients suggests necessity real-world study vaccine benefit–risk profile. In this study, we evaluated efficacy and safe...

A primary anti-NIP PFC response can be elicited by a GVH reaction provided certain structural requirements of the NIP-carrier are met. NIP-coated F(1) erythrocytes and NIP-coated parental erythrocytes give rise to substantial anti-NIP PFC responses in F(1) mice after the injection of parental spleens. These conjugates do not of themselves give rise to an anti-NIP PFC response and, in fact, norm...

The hunt for an effective vaccine against malaria still continues. Several new target antigens as candidates for vaccine design are being explored and tested for their efficacy. In the present study the sera from mice immunized with 24,000 x g fraction of Plasmodium berghei has been used to identify highly immunogenic blood stage antigens. The protective antibodies present in immune sera were c...

Most malignant cells are poorly immunogenic and fail to elicit an effective antitumor immune response. In contrast, viral infections of cells are promptly detected and eliminated by the immune system. Viral recognition critically hinges on cytosolic nucleic acid receptors that include the proinflammatory RNA helicase retinoic acid-inducible gene-I (RIG-I). Here, we show that targeted delivery o...

Melanoma is an immunogenic cancer. However, the ability of the immune system to eradicate melanoma tumors is affected by intrinsic negative regulatory mechanisms. Multiple immune-modulatory therapies are currently being developed to optimize the immune response to melanoma tumors. Two recent Phase III studies using the monoclonal antibody ipilimumab, which targets the cytotoxic T-lymphocyte ant...

The immunogenicity of long-surviving, enhanced (AS X AUG)F1 renal allografts retransplanted into secondary AS recipients was restored by the injection of small numbers of donor strain dendritic cells derived from afferent lymph. Whereas 1 X 10(4) to 5 X 10(4) dendritic cells were able to trigger an acute rejection response, neither the passenger volume of donor strain blood nor 5 X 10(6) T or B...

The term "immunogenic cell death" (ICD) is commonly employed to indicate a peculiar instance of regulated cell death (RCD) that engages the adaptive arm of the immune system. The inoculation of cancer cells undergoing ICD into immunocompetent animals elicits a specific immune response associated with the establishment of immunological memory. Only a few agents are intrinsically endowed with the...
