We developed an influenza hemagglutinin (HA) pseudotype library encompassing Influenza A subtypes HA1-18 and B (both lineages) to be employed in microneutralization (pMN) assays. The pMN is highly sensitive specific for detecting virus-specific neutralizing antibodies against viruses can used assess antibody functionality vitro. Here we show the production of these viral HA pseudotypes their em...

Recent analyses of immunologic specificity have demonstrated that, to a considerable extent, antigenic recognition involves not only the recognition of extrinsic antigenic determinants per se, but also the recognition of determinants contributed by antigen-presenting cells. For example, antigen-specific T helper ceils are restricted in collaboration to cells syngeneic with the antigen-presentin...

Purpose: Among all known human coronaviruses, some viruses (e.g., SARS-CoV-2) cause severe pneumonia or even death. With the regard to its spread and importance of rapid identification/treatment, because pAbs are relatively cheap, able bind more sites on antigens neutralize them, this study was done for production purification anti-SARS-CoV-2 polyclonal antibodies (pAb) in rats. Methods: Viral ...

SARS-CoV-2 is the third pathogenic coronavirus to emerge since 2000. Experience from prior outbreaks of SARS-CoV and MERS-CoV has demonstrated importance both humoral cellular immunity clinical outcome, precepts that have been recapitulated for SARS-CoV-2. Despite unprecedented rapid development deployment vaccines against SARS-CoV-2, more are needed meet global demand guard immune evasion by n...

Viral infection is sometimes associated with the initiation or exacerbation of autoimmune disease, although the underlying mechanisms remain unclear. One proposed mechanism is that viral determinants that mimic host antigens trigger self-reactive T cell clones to destroy host tissue. An epitope expressed by a coat protein of herpes simplex virus-type 1 (HSV-1) KOS strain has now been shown to b...

Diagnosis of infectious diseases remains an important issue in medical science. Identification of biomarkers can be used to predict early infections. Recently, heat shock proteins (HSPs) have been known as the conserved compounds expressed under stress conditions in both prokaryotic and eukaryotic systems. These proteins act as molecular chaperones. Several studies showed the increased levels o...

Proof-of-concept studies have demonstrated the therapeutic potential of engineered T cells. Transfer of recombinant antigen-specific T cell receptors (TCR) and chimaeric antigen receptors (CARs) against tumour and viral antigens are under investigation by multiple approaches, including viral- and nonviral-mediated gene transfer into both autologous and allogeneic T cell populations. There have ...

T cell immunity is critical in controlling human cytomegalovirus (HCMV) infection in transplant recipients, and T cells targeting viral immediate early proteins such as IE1, IE2 and pp65 have been speculated to be more effective against reactivation. Here we report efforts to construct replication incompetent adenovirus 6 vectors expressing these viral antigens as vaccine candidates. To reduce ...
