Immune system Flashcards
Immune system
What are the 4 types of breast cancer
Luminal A
Luminal B
Luminal HER2
Basal-like: HR- and HER2-
What is characteristic of Lumina A
Low ki-67
Low proliferation
HER2-negative
Luminal B characteristics
ER-positive cells
high Ki-67 expression
HER2 negative and one of worst prognosis
Luminal HER2 characteristics
ER- positive cells and HER2- positive
HER2- enriched
Basal like characterstics
HR- negative
HER2 negative
described as unruly teenagers
What is prognosis adversely affected by
ER negative PR negative HER2 positive Elevated Ki-67 Higher tumor grade Lower albumin Lymphovascular invasion BRCA status
What is the most important prognostic marker for breast cancer
tumor size and presence of malignant disease in regional lymph nodes
Prognostic biomarkers of breast cancer
Vitamin D- low associated with breast cancer Circulating Tumor cells COMT- estrogen metabolites( 3 URT) IGF-1: insulin Growth Factor1- stimulate cancer cell proliferation C-peptide( insulin) Galactin-3 Cortisol function Thyroid Function Various inflammation biomarkers
What are natural breast cancer strategies
Diet: high amount fruit, veggies, poultry, fish, low fat dairy and whole grain Weight Fat intake Soy- reduce risk of breast cancer Exercise- 2.5 hours of moderate physical activity Sleep Stress management Dietary supplements
Causes of autoimmunity
stress in all forms: toxic, infectious, inflammatory, emotional and cognitive, Hormonal, GI
What percent of population have reactions to foods
20%
What are the 4 yes of food sensitivty
IgE- reaction- occurs within 2 hours of eating- release histamine
IgG or IgM- delayed hypersensitivity
Immune complex- delay hypersensitivty- days to weeks
Cell mediated delayed hypersensitvity
What is the chain reaction for food sensitivities/allergies
allergen->immune detect particle->release antibody as needed to pathogen->release histamine, photolytic enzymes or leuokotyine and cytokines-> allergic reaction
Symptoms of immediate onset allergy/sensitvity
tighten of throat, nasuea, cramps, diarrhea, anaphylaxis can happen- immune reaction will almost always provoke with single food- fixed food allergy
Tests to diagnose food allergies/sensitvities
Prick test
Intradermal test
Elimination Diet
RAST test
Types of Immunological Allergy testing
IgG testing-75% of all circulating antibodies, delayed response IgG(4)- slow occurring 24-48 hours later IgG and IgA- mediated food allergy, ALCAT Sage ELISA delayed food allergy test
What is the ALCAT test
Antigen Leukocyte Cellular Antibody Test
-look at leukocyte in whole blood
relies on one specific pathway
What is Sage ELISA test
looks at IgG and immune complexes at different levels-specifically IgG2 and 3 reactions
Most comprehensive test for delayed food reactions
What is Secratory IgA
first line of defense
lives in nose and lungs
What are defenses of SigA
non-specific
covers invasion like an orange with cloves
is only immunoglobulin that does its work without creating an systemic response
decreases body’s secretions, decrease immune defense
targets against macrophages and anything that might be harmful
Where does sigA come from
B-Lymphocytes
attaches and enters gut lumen
Peyer’s patches play a role
What are function of sigA
inhibition of adherence to pathogen
Mucus trapping
Viral neutralization
Neutralization of enzyme and toxin
Inhibition of antigen penetration into intestinal lining
Interaction with antimicrobial factors such as lactoferrin and lysozyme
Involved in oral toerlance
What are Roles of sigA
target microorganism that don’t have right identifier
prevent inflammation
maintain integrity of lining of gut barrier
What suppresses sigA
cortisol- especially bottomed out
