Antibodies are immune system-related proteins called immunoglobulins. Each antibody consists of four polypeptides– two heavy chains and two light chains joined to form a "Y" shaped molecule. ... This variable region, composed of 110-130 amino acids, give the antibody its specificity for binding antigen.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Fig. 2.8, part 1 of 2. Overview of the main components and effector actions of complement. The early events of all three pathways of complement activation involve a series of cleavage reactions that culminate in the formation of an enzymatic activity called a C3 convertase, which cleaves complement component C3 into C3b and C3a. The production of the C3 convertase is the point at which the three pathways converge and the main effector functions of complement are generated. C3b binds covalently to the bacterial cell membrane and opsonizes the bacteria, enabling phagocytes to internalize them. C3a is a peptide mediator of local inflammation. C5a and C5b are generated by cleavage of C5b by a C5 convertase formed by C3b bound to the C3 convertase (not shown in this simplified diagram). C5a is also a powerful peptide mediator of inflammation. C5b triggers the late events in which the terminal components of complement assemble into a membrane-attack complex that can damage the membrane of certain pathogens. C4a is generated by the cleavage of C4 during the early events of the classical pathway, and not by the action of C3 convertase, hence the *; it is also a peptide mediator of inflammation but its effects are relatively weak. Similarly, C4b, the large cleavage fragment of C4 (not shown), is a weak opsonin. Although the classical complement activation pathway was first discovered as an antibody-triggered pathway, it is now known that C1q can activate this pathway by binding directly to pathogen surfaces, as well as paralleling the MB-lectin activation pathway by binding to antibody that is itself bound to the pathogen surface. In the MB-lectin pathway, MASP stands for mannan-binding lectin-associated serine protease. MBL important in early childhood and essentially act in lieu of antibodies C4 cleavage exposes thioester bond that covalently bonds to nearest surface Alternate pathway does not depend on a pathogen binding protein (spontaneous cleavage of C3)
Non adaptive recognition receptors called Pathogen Recognition Receptors (PRR). These recognize PAMPs or pathogen associated molecular patterns. This leads to activation of immune response. Receptors can exist on the surface of the cell or intracellular in endocytic compartments. Recognition is based on two principles 1. microbial non-self (PRR/PAMP) 2. Missing self Inhibitory receptors (NK cells) Factor H of Complement In this lecture we will focus on receptors that recognize the pathogen. NK cells will be discussed later and you have already discussed complement. However, we will touch on the receptors of the complement system that the innate immune system uses for recognition. Example: Recognition of a pathogen causes to signals to be released. co-stimulator signals cytokines
