Study Notes
Rejection in Organ Transplantation
- Rejection depends on the number of mismatches
- Lower mismatches are better
- Men have a more complicated process than women; require Y matching in addition to major histocompatibility antigens.
Graft Versus Host Disease (GVHD)
- GVHD can sometimes help with certain cancers like blood cancers (leukemia)
- GVHD can affect blood cancers in a good way since it targets the cancer cells, not the host
Transplantation Nuances
- HLA haploidentical family members are typically the preferred donors for transplantation
- This is frequently more likely if numerous siblings exist
- Cousins can also be similar enough genetically
- Alloreactive NK cells can help in transplantations, particularly with haploidentical transplants.
Cancer
- Cancer is the second leading cause of death in the US, 2019.
- Cancer affects many organs and cell types
- The idea of one cure for all cancer types is improbable
- Cancer is the uncontrolled growth and division of cells, due to mutations
Cancer Detection
- Cancer can be detected by medical imaging, such as x-rays and mammograms.
- Early detection is crucial and often leads to better treatment outcomes.
- Early-stage cancer detection often leads to more aggressive treatments like targeted therapy
Immunological Techniques for Cancer Treatment
- Antibodies targeting tumor antigens can eliminate the cancer or cause it to die naturally
- The advantage of antibody treatment is that it is very targeted, unlike chemotherapy, which is non-specific and can cause damage to healthy cells
- The ability to identify a specific marker on a cancer cell helps to create very powerful treatments
Cancer Growth and Spread
- Cancer usually grows slowly over time. However, it depends on the type of cells involved.
- Cancer cells can become more aggressive and invasive
- Cancer can spread from its origin to other tissues, a process called metastasis.
- Metastasis can occur in multiple different systems, making it harder to treat overall.
- The doubling of cancer cells is a key indicator of how rapidly a tumor is growing
Oncogenic and Tumor Suppressor Genes
- Oncogenes promote abnormal cell growth.
- Tumor suppressor genes can slow down cell growth.
- Mutations in these genes can lead to uncontrolled cell division, which is a hallmark of cancer.
