Linear carbohydrate-peptide constructs based on the 13 amino acid nonnatural pan DR epitope (PADRE) and carbohydrate B cell epitopes are demonstrated to be potent immunogens. These data support our belief that PADRE should be considered as an alternative to more complex carriers for use in prophylaxis and therapeutic vaccines. Two model carbohydrate-PADRE glycoconjugates were used to demonstrat...

Aspergillus fumigatus is a pathogenic microorganism that causes aspergillosis due to the presence of its allergenic proteins. During last two years, few clinical cases have been reported where allergic bronchopulmonary (ABPA) has detected in COVID-19 patients. The administration antifungal medicine did not provide satisfactory results. It challenging job for medical scientists protect mankind b...

Background:  Cytotoxic T lymphocyte–associated antigen 4 (CTLA-4) molecules are expressed on T-cells and inhibit their function by inhibiting activation of subsequent T-cell molecular pathways. Blocking of CTLA-4 inhibits the growth of malignant tumor cells. Anti-CTLA-4 monoclonal antibodies activate the immune system against cancer. Due to several advantages of single-chain antibodi...

a random 12 mers phage library was used to screen a pool of immunoglo¬bulin fractions obtained from vitiligo patients. subsequent to panning experiments, a panel of affinity selected phage from vitiligo patients were obtained. this panel was tested using an elis a for their reactivity with pooled sera from patients and normal controls. among the 16 randomly selected clones, two of clones showed...
