A synthetic peptide sp2 has the amino acid sequence shown in SEQ ID No: 1. sp2 has obvious anti-tumor growth activity on xenograft tumours such as subcutaneous human pancreatic cancer, human cervical cancer, and human ovarian cancer in nude mice, with a dose-effect and time-effect relation; and has the effect of delaying metastasis and prolonging the survival time of nude mouse having in situ transplantation of human pancreatic cancer and lung adenocarcinoma. After the animals were given intravenous injection of sp2 at a dose of 2000 mg/kgBW, no toxicity reaction and death were observed. The applications of sp2 also include: (1) preventing and/or treating of tumor; (2) inhibiting proliferation and/or growth and/or invasion of tumor cells; (3) enhancing the anti-tumor immune response; (4) inducing tumor cell differentiation; (5) preparing anti-tumor drugs; (6) inhibiting tumor telomerase activity; and (7) regulating the tumor cell cycle.

The invention provides chimeric antigen receptor(s) (CAR(s)) that comprise a fusion protein of CTX or any functional variant thereof or a CTX-like peptide or any functional variant thereof as the extracellular antigen recognition moiety of the CAR. CAR(s) comprising CTX, a CTX-like peptide or functional variants of the foregoing are collectively referred to herein as “CTX-CAR(s).” Such CTX-CAR(s) may further comprise additional moieties or domains in the extracellular domain, a transmembrane domain and at least one intracellular signaling domain. Such CTX-CAR(s) may be expressed in a host cell, such as, but not limited to, an immune effector cell. The present invention also provides methods of treatment (such as, for example, methods for treating cancer) by providing to the patient in need thereof immune effector cells that arc engineered to express a CTX-CAR described herein.

Disclosed herein are immunoglobulin fusion proteins comprising a first antibody region, a first therapeutic agent, and a first connecting peptide; wherein the first therapeutic agent is attached to the first antibody region by the connecting peptide; and wherein the connecting peptide does not comprise a region having beta strand secondary structure. The connecting peptide may comprise an extender peptide. The extender peptide may have an alpha helical secondary structure. The connecting peptide may comprise a linker peptide. The linker peptide may not comprise any secondary structure. Also disclosed herein are compositions comprising the immunoglobulin fusion proteins and methods for using the immunoglobulin fusion proteins for the treatment or prevention of a disease or condition in a subject.
