Soluble CD4 antigens in the cerebrospinal fluid as a marker of lymphocytic infiltration of the central nervous system [PDF]

open access: yesVojnosanitetski Pregled, 2004
Early diagnosis of the central nervous system (CNS) infections is a precondition of their successful treatment. However, the essential standard examination of the cerebrospinal fluid (CSF) is sometimes neither specific enough to define their basic nature,

Antigenic Variability [PDF]

open access: yesFrontiers in Immunology, 2020
Protective vaccines for hypervariable pathogens are urgently needed. It has been proposed that amputating highly variable epitopes from vaccine antigens would induce the production of broadly protective antibodies targeting conserved epitopes. However, so far, these approaches have failed, partially because conserved epitopes are occluded in vivo and ...

Antigen Stability Controls Antigen Presentation [PDF]

open access: yesJournal of Biological Chemistry, 2004
We investigated whether protein stability controls antigen presentation using a four disulfide-containing snake toxin and three derivatives carrying one or two mutations (L1A, L1A/H4Y, and H4Y). These mutations were anticipated to increase (H4Y) or decrease (L1A) the antigen non-covalent stabilizing interactions, H4Y being naturally and frequently ...

Comprehensive Characterization of Reference Standard Lots of HIV-1 Subtype C Gp120 Proteins for Clinical Trials in Southern African Regions

open access: yesVaccines, 2016
Two HIV-1 subtype C gp120 protein candidates were the selected antigens for several experimental vaccine regimens now under evaluation in HVTN 100 Phase I/II clinical trial aiming to support the start of the HVTN 702 Phase IIb/III trial in southern ...

Identificación de antígenos de aislamientos colombianos de Giardia duodenalis reconocidos por IgG total y subclases.

open access: yesBiomédica: revista del Instituto Nacional de Salud, 2003
Se conocen investigaciones realizadas sobre la respuesta inmune humoral en giardiosis. Sin embargo, estudios sobre perfiles de antígenos de quistes y de trofozoítos de Giardia duodenalis reconocidos por IgG y subclases (IgG1, IgG2, IgG3, IgG4) anti-G ...

Binding to Nanopatterned Antigens is Dominated by the Spatial Tolerance of Antibodies

open access: yesNature Nanotechnology, 2018
Although repetitive patterns of antigens are crucial for certain immune responses, an understanding of how antibodies bind and dynamically interact with various spatial arrangements of molecules is lacking.

Molecular typing of RhD-negative blood donors with C and/or E antigen [PDF]

open access: yesScripta Medica, 2019
Background: Most people are either RhD positive or RhD negative, but there is also a number of persons with D antigen variants. The aim of this study was to prove, by using molecular diagnostic tests, whether the RHD gene and D antigen on the red cell ...

Nanoparticle Vaccines Against Infectious Diseases

open access: yesFrontiers in Immunology, 2018
Due to emergence of new variants of pathogenic micro-organisms the treatment and immunization of infectious diseases have become a great challenge in the past few years.

Discriminating antigen and non-antigen using proteome dissimilarity: bacterial antigens [PDF]

open access: yesBioinformation, 2010
It has been postulated that immunogenicity results from the overall dissimilarity of pathogenic proteins versus the host proteome. We have sought to use this concept to discriminate between antigens and non-antigens of bacterial origin. Sets of 100 known antigenic and nonantigenic peptide sequences from bacteria were compared to human and mouse ...

Expansion of host range as a driving force in the evolution of Toxoplasma

open access: yesMemorias do Instituto Oswaldo Cruz, 2009
The apicomplexan parasite Toxoplasma gondii is unusual in being able to infect almost any cell from almost any warm-blooded animal it encounters. This extraordinary host-range contrasts with its far more particular cousins such as the various species of ...
