Co-expression of CD40L with CD70 or OX40L increases B-cell viability and antitumor efficacy

Co-expression of CD40L with CD70 or OX40L increases B-cell viability and antitumor efficacy

Activated B-cells are a promising alternative source of antigen-presenting cells. They can generally be obtained in sufficient numbers for clinical use, but in most instances produce weak immune responses and therapeutic effects that are suboptimal for use in therapeutic cancer vaccines. To improve the immunogenic potency and therapeutic efficacy of B-cell-based vaccines, ex vivo-activated B-ce...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Multimeric forms of CD40 ligand (CD40L), 4-1BB ligand (4-1BBL), OX40 ligand (OX40L), CD27L/CD70, and other TNFSFs as tools for adoptive cell therapy

The TNF SuperFamily (TNFSF) of ligands include 19 molecules some of which play key roles in the immune system. All of these ligands are produced as trimeric Type II membrane molecules that can be released from the cell surface as single trimers. However, more than a decade of research has shown that the receptors for TNFSFs on responding cells require clustering in order to signal. Thus, single...

In vivo antitumor effect of CD40L-transduced tumor cells as a vaccine for B-cell lymphoma.

CD40-CD40 ligand (CD40L) interactions play a critical role in the activationof cellular immunity. CD40L enhances the antigen presentation function of CD40-expressing B cells. We have used a murine B-cell lymphoma model (A20) to study the in vivo antitumor effect of the administration of tumor cells transduced with a recombinant adenovirus encoding CD40L (AdvCD40L). After infection with AdvCD40L...
