The effect of thyme essential oil and endothelial progenitor stem cells on lipopolysaccharide-induced sepsis in C57BL/6 mice.

Sepsis is a potentially fatal syndrome related to severe systemic inflammation developed by infection. Despite different antimicrobial therapies, morbidity and mortality rates remain high. Herbs along with cell therapy have been introduced as a promising option to improve the symptoms of sepsis.

Novel neutralizing mouse-human chimeric monoclonal antibodies against the SARS-CoV-2 receptor binding domain.

Neutralizing antibodies have been widely used for the prophylaxis and treatment of COVID-19. The major target for these neutralizing antibodies is the receptor-binding domain (RBD) of the viral spike protein. In the present study, we developed and characterized three neutralizing chimeric mouse-human mAbs for potential therapeutic purposes.

Immunization with placenta-specific 1 (plac1) induces potent anti-tumor responses and prolongs survival in a mouse model of melanoma.

Purpose: Melanoma is a malignant and metastatic form of skin cancer, which is not diagnosed in early stages of the disease. Nowadays, immunotherapy is changing the treatment landscape for metastatic melanoma. Placenta-specific1 (PLAC1) is a cancer-testis-placenta (CTP) antigen with differential expression in melanoma tissues.

Optimization of Expression and Purification of Recombinant Mouse plac1.

Background: Placenta-specific 1 (PLAC1) is one of the recently-discovered Cancer-Testis-Placenta (CTP) antigen with restricted normal tissue and ectopic expression in a wide range of cancer cells from different histological origins. The production of recombinant human PLAC1 has already been optimized; however, no study has been reported so far on the production and purification of mouse plac1. In this study, mouse plac1 expression and purification was optimized in a prokaryotic system and the effects of the generated proteins on inducing humoral responses in mice were investigated.

Design and evaluation of a hypoallergenic peptide-based vaccine for Salsola kali allergy.

Background: The Salsola kali (S. kali) pollen is one of the most important causes of allergic rhinitis in the deserts and semi-desert areas. Immunotherapy with allergen extracts remains the only available treatment addressing the underlying mechanism of allergy.

Myeloid-derived Suppressor Cells Elimination by 5-Fluorouracil Increased Dendritic Cell-based Vaccine Function and Improved Immunity in Tumor Mice.

Myeloid-derived suppressor cells (MDSCs) are capable of suppressing the immune response. 5-Fluorouracil (5-FU) compared to other chemotherapy drugs have shown considerable decreases in the number of MDSCs without visible effects on T, B and natural killer cells, as well as dendritic cells (DCs). DC-based vaccines considered to be appropriate candidates for cancer immunotherapy.

Study of curcumin immunomodulatory effects on reactive astrocyte cell function.

Multiple sclerosis (MS) is considered an inflammatory and neurodegenerative disease of the central nervous system (CNS) which most often presents as relapsing-remitting episodes. Recent evidence suggests that activated astrocytes play a dual functional role in CNS inflammatory disorders such as MS. In this study, we tried to induce anti-inflammatory functions of astrocytes by curcumin.
