INTRODUCTION
TO
IMMUNOLOGY
(Part 2)
- Development of
T and B cells
- Lymphocytes
- COLONEL DELETION occurs to eliminate lymphocytes
- Antigen-independent
maturation
- T cells :
Thymus
- B cells :
Bone
marrow
- Surface Markers
or Receptors
- Bind to
receptors
on other
cells
- Bind to
antigens
- Transmit
and
receives
messages
- Common receptor molecuules
- MHC
- CD
- Antigen-specific
receptors
- Presentation of
Antigens
- substances that can provoke
immune response
- many EPITOPES
- determine by SIZE, COMPLEXITY &
FOREIGNNESS
- presented by APCs
- Macrophages
- Dendritic cells
- B cells
- T cells : TCR
- supported by CD4 or CD8
- B cells : Immunoglobulins or Antibodies
- IgG, IgA, IgM, IgE, IgD
- T - cell Response
- Subtypes of T helper
cells
- stimulate or
activate
other cells
- Memory
- immmunological
memory
- Regulatory
- prevent excessive
inflammation &
autoimmunity
- Cytotoxic
- infected
host
cells
- cancerous
host
cells
- Foreign
cells
- B - cell Response
- SOMETIMES, can be activated by T
helper : T independent activation
- MOST OF THE TIME, require
activation of T helper cells
- Memory
- store
immunological
memory
- Antibodies
- Neutralisation
- Opsonisation
- Agglutination
- Antitoxin action
