Article history: Received 25 July 2016 Accepted 25 July 2016 Available online 27 July 2016 small amounts ofM and L protein asminor components of S-HBsAg particles. It has superior immunogenicity (Shouval et al., 2015), but it remains open whether this is due to the preS components or to better immunogenicity of the S part. Isolated preS antigen without HBsAg had generated neutralizing antibodie...

Immune responses can make protein therapeutics ineffective or even dangerous. We describe a general computational protein design method for reducing immunogenicity by eliminating known and predicted T-cell epitopes and maximizing the content of human peptide sequences without disrupting protein structure and function. We show that the method recapitulates previous experimental results on immuno...

This Viewpoint proposes that Medicare claims data could inform the rollout of a COVID-19 vaccination program in US, including notifying beneficiaries their risk and prioritization supporting efforts to allocate vaccine monitor its uptake, immunogenicity, safety.

Active immunization with the idiotype of follicular lymphoma induces tumor-specific immunity. T cells induced in vivo by idiotype vaccination recognize human leukocyte antigen (HLA)--restricted hypervariable but not conserved idiotype peptides. We hypothesized that idiotype-directed T-cell immunity occurs naturally and performed a reverse immunology analysis of idiotype HLA binding in 39 follic...

BACKGROUND Alloimmunization against human platelet antigens (HPAs) during pregnancy is rare but can lead to severe bleeding disorders, such as fetal and neonatal alloimmune thrombocytopenia. STUDY DESIGN AND METHODS In a cohort of 241 uncomplicated pregnancies, we investigated the immunogenicity of HPA mismatches and correlated HLA sensitization with HPA antibody formation. HPA antibodies wer...

A comparison of the immunogenicity of sodium deoxycholate-disrupted lipopolysaccharides from Escherichia coli cell walls revealed that these fragments, which are nonimmunogenic in the rabbit, have some activity in the mouse. This relationship was independent of the route of immunization and sex, but in both species immunogenicity was restored by dilution or dialysis. Adsorption of disrupted lip...

Viral subunit vaccines often contain immunodominant non-neutralizing epitopes that divert host immune responses. These epitopes should be eliminated in vaccine design, but there is no reliable method for evaluating an epitope's capacity to elicit neutralizing immune responses. Here we introduce a new concept 'neutralizing immunogenicity index' (NII) to evaluate an epitope's neutralizing immunog...

Circumsporozoite protein (CSP) of Plasmodium falciparum is a promising malaria vaccine target. RTS,S, the most advanced malaria vaccine candidate consists of the central NANP repeat and carboxy-terminal region of CSP displayed on a hepatitis B virus-like particle (VLP). To build upon the success of RTS,S, we produced a near full-length Plasmodium falciparum CSP that also includes the conserved ...

Immunogenicity of biological agents leads to the development of anti-drug antibodies (ADA) and it may be associated to all biologicals irrespective of the presence of xenoantigens. Several drug-, patients-, diseaseand treatment-related factors contribute to immunogenicity. Low ADA levels can influence the efficacy of the drugs, whereas high levels can induce hypersentivity reactions. Immediate ...

Immune responses to some monoclonal antibodies (mAbs) and biologic proteins interfere with their efficacy due to the development of anti-drug antibodies (ADA). In the case of mAbs, most ADA target 'foreign' sequences present in the complementarity determining regions (CDRs). Humanization of the mAb sequence is one approach that has been used to render biologics less foreign to the human immune ...
