Prime-Boost Vaccination with Toxoplasma Lysate Antigen, but Not with a Mixture of Recombinant Protein Antigens, Leads to Reduction of Brain Cyst Formation in BALB/c Mice
PublikacjaIntroduction Infection with the ubiquitous parasite Toxoplasma gondii is a threat for immunocompro- mised patients and pregnant women and effective immune-prophylaxis is still lacking. Methods Here we tested a mixture of recombinant T . gondii antigens expressed in different develop- mental stages, i.e., SAG1, MAG1 and GRA7 (SMG), and a lysate derived from T . gondii tachyzoites (TLA) for prophylactic vaccination against cyst formation....

Toxoplasma gondii: an evaluation of diagnostic value of recombinant antigens in a murine model
PublikacjaPraca dotyczy oceny użyteczności sześciu rekombinantowych białek antygenowych Toxoplasma gondii (GRA1, GRA6, GRA7, p35, SAG1 i SAG2) w diagnozowaniu doświadczalnej toksoplazmozy u myszy. Przeprowadzone badania pozwoliły na określenie stopnia reaktywności zastosowanych antygenów z surowicami z wczesnej i przewlekłej toksoplazmozy. W przypadku ostrej fazy choroby obserwowano silną odpowiedź humoralną na antygeny GRA7, GRA6 i p35,...

Toxoplasma gondii Recombinant Antigens in the Serodiagnosis of Toxoplasmosis in Domestic and Farm Animals
PublikacjaToxoplasmosis is caused by an intracellular protozoan, Toxoplasma gondii, and is a parasitic disease that occurs in all warm-blooded animals, including humans. Toxoplasmosis is one of the most common parasitic diseases of animals and results in reproductive losses. Toxoplasmosis in humans is usually caused by eating raw or undercooked meat or consuming dairy products containing the parasite. Diagnosis of toxoplasmosis is currently...

A new MIC1-MAG1 recombinant chimeric antigen can be used instead of the Toxoplasma lysate antigen in the serodiagnosis of human toxoplasmosis
PublikacjaW niniejszej publikacji po raz pierwszy przedstawiono otrzymanie i oszacowanie przydatności diagnostycznej nowego chimerycznego antygenu MIC1-MAG1 Toxoplasma gondii do rozpoznawania toksoplazmozy u ludzi. Antygen chimeryczny MIC1-MAG1 został otrzymany jako białko fuzyjne zawierające dwie domeny oligohistydynowe na N- i C-końcu z użyciem systemu ekspresyjnego Escherichia coli. Po oczyszczeniu z wykorzystaniem metody chromatografii...

Testing the Diagnostic Utility of Recombinant Toxoplasma Gondii Chimeric Antigens – Generated Datasets
PublikacjaThe datasets titled Toxoplasma gondii recombinant chimeric antigens – IgM and IgG ELISAs – mouse serum samples and Toxoplasma gondii recombinant chimeric antigens – IgG and IgM ELISAs – human serum samples contain absorbance measurements obtained during serological tests using mouse and human sera in enzyme-linked immunosorbent assay (ELISA) tests based on recombinant chimeric antigens. The datasets allows a comparison of absorbance...

Cancer immune escape: the role of antigen presentation machinery
PublikacjaThe mechanisms of antigen processing and presentation play a crucial role in the recognition and targeting of cancer cells by the immune system. Cancer cells can evade the immune system by downregulating or losing the expression of the proteins recognized by the immune cells as antigens, creating an immunosuppressive microenvironment, and altering their ability to process and present antigens. This review focuses on the mechanisms...

Toxoplasma gondii recombinant antigens as tools for serodiagnosis of human toxoplasmosis: current status of studies
PublikacjaToxoplasma gondii is a parasitic protozoan which is the cause of toxoplasmosis. Although human toxoplasmosis in healthy adults is usually asymptomatic, serious disease can occur in the case of congenital infections and immunocompromised individuals. Furthermore, despite the exact recognition of its etiology, it still presents a diagnostic problem. Diagnosis of toxoplasmosis is mainly based on the results of serological tests detecting...

In silico epitope prediction of Borrelia burgdorferi sensu lato antigens for the detection of specific antibodies
PublikacjaDespite many years of research, serodiagnosis of Lyme disease still faces many obstacles. Difficulties arise mainly due to the low degree of amino acid sequence conservation of the most immunogenic antigens among B. burgdorferi s.l. genospecies, as well as differences in protein production depending on the environment in which the spirochete is located. Mapping B-cell epitopes located on antigens allows for a better understanding...
