Forms of Cancer Immunotherapy
• Non-Specific: Generalized, Non-Antigen-Specific Immune Activation
• Specific: Antigen-specific Response Induced in the Mouse or Patient or Passively Transferred in from Donor Source
ImmForm1
Forms of Cancer Immunotherapy
Active: Induced Directly in the Tumor-Bearing Animal or in the Patient
• Can be Specific or Non Specific
Passive or Adoptive: Immunologically Active Material Transferred into Mouse or Patient as a Passive Recipient
• Can be Specific (Antibodies, T-Cells, Antigen-presenting cells – Dendritic Cell Vaccines)
• Or Non-Specific (Non-specifically-activated T-Cells; Cytokines ImmForm2
Active Non-Specific Immunotherapy
Bacterial Extracts: Non-Specific Immune Adjuvants• BCG: Bacillus Calmette-Guerin (Attenuated Bovine
Tuberculosis Bacterium)• Membrane Extracts of BCG • C Parvum: Corynebacterium parvum (related to diphtheria
bacillus)Bacterial Endotoxins: Muramyl DipeptideChemical Adjuvants: • Levamisole• Poly IC (Poly-inosinic-Poly-cytidyllic acid)Cytokines: (Can be actively induced or passively transferred)• Interferons• Interleukin 2 (IL2)• Tumor Necrosis Factor (TNF)

Example of Cytokines in Immunotherpay of Cancer (Passive or Active)
Adoptive Immunotherapy of Cancers(Passive: Donor to Recipient)
Non-Specific:• Lymphokine-activated Killer Cells (LAK Cells)\• Cytokines
Specific: Molecular Transfer• Monoclonal Antibodies
Specific: Cellular Transfer• Tumor-Infiltrating Lymphocytes (TIL Cells)• Engineered Antigen-Presenting Cells (Dendritic
Cells)
Adoptive
Some Examples of Active, Specific Immunotherapy
(Tumor Vaccines)Unmodified Killed or Attenuated Tumor CellsUnmodified Tumor AntigensAltered Tumor Cells or Tumor Antigens• Lipidized Tumor Antigens• Chemically Derivatized Tumor Antigens• "Xenogenized" Tumor Cells (Virally-infected Cells)• Exposure of Cryptic AntigensAntigenic Peptides from Tumor Antigens

Autologous Tumor Cells Vaccine for Glioblastoma Multiforme
April , 2012
50% increase in survival time (48 weeks vs 33 weeks)Minimal side –reactions
40 Patients
http://gma.yahoo.com/brain-tumor-vaccine-shows-promise-early-trial-160209936.html
A phase 2 multicenter trial of about 40 patients with recurrent glioblastoma -- an aggressive brain cancer that typically kills patients within 15 months of diagnosis -- showed that the vaccine safely increased average survival to nearly 48 weeks, compared with about 33 weeks among patients who didn't receive the treatment. The six-month survival rate was 93 percent for the vaccinated group, compared with 68 percent for 86 other glioblastoma patients, who were treated with other therapies.
Applications of Monoclonal AntibodiesMonoclonal Antibody Diagnosis and Tumor-
Imaging• Prostate-specific Antigen (PSA)• Carcino-embryonic Antigen (CEA)• Colon Carcinoma A33 Antigen
Monoclonal Antibody Targeting• Immuno-toxins• Monoclonal antibodies directed to tumor cell
surface markers– Can inhibit the cancer cell function– Can target the cancer cell for destruction by the
immune responseCxMonoAb

The Endless Mirrors
What will remain when our days are done?What will matter when we are gone?
That we stalked the crumbled halls of power?Were known by men long lost to time?
Famed in some forgotten hour?
Or that we wrote a song still sung?Penned a verse that touches souls?
Shaped a cure to solace fearsTo offer hope, to tarry death
for childhood’s child in endless years?
Birthed a thought that sired ten more?Conceived a dream and passed it on?
Forged a link from gone to be,And shined our candle in the endless mirrors
That reflect forever down the halls of time.

With respect to the use of the Turning Point XR-Transmitter System
This response is set at anonymous. You will not be identified with your answer, only that you are responding.
1. This is a disaster! Forget about it!2. This system is not very good. It has a long
way to go to be a useful part of Biology courses, but it is worth working on.
3. The XR system is OK. It is worth keeping and using if you can make it work better.
4. The system was actually pretty cool. It made an important contribution to the standards in BIO 501.
5. The use of the XR system was an exciting advance in group communication in the classroom.
